Hello. Plz tell me, where i can find detailed information about my Radeon 
x1250. Something like this:
if ((rdev->pdev->device == 0x791f) &&
(rdev->pdev->subsystem_vendor == 0x1028) &&
(rdev->pdev->subsystem_device == 0x01fc))
Simple hack "return true;" work.
Notebook: Emachines D620
Thanks.

Title:
  [RS690M] No 3d acceleration in Radeon X1200 with new Gallium r300 / 3d
  drivers in 11.04 (Needs kernel quirk)

Status in The Linux Kernel:
  Fix Committed
Status in X.org XServer - ATI gfx chipset driver:
  Confirmed
Status in “xserver-xorg-video-ati” package in Ubuntu:
  Triaged
Status in Fedora:
  Unknown

Bug description:
  The bug is active also in Freedesktop.org :
  https://bugs.freedesktop.org/show_bug.cgi?id=37679

  [edit]
  The bug seems to be fixed with a patch provided by Freedesktop.org team.
  [/edit]

  [edit]
  This bug is caused by interrupts. They're not working. The solution for this 
problem is:
  - To see if Ubuntu 10.04 (where all things worked well) used UMS instead of 
KMS.
  - If Lucid used KMS, to bisect the kernel to see what change caused the 
problem.

  [/edit]

  [edit]
  The bug description, updated:

  The symptoms: No 3d acceleration (glxgears shows a black window, Unity
  doesn't start), *but* no fallback into the software-rendering mode
  (glxinfo reports that the 3d acceleration is working)

  The hardware: ATI Radeon RS690M X1200 series

  The version of Ubuntu: Ubuntu 11.04 (final release) [and Maverick
  also]. The behavior was also observed in Debian and Fedora 15, as
  noted below (so it seems not to be Ubuntu-specific).

  The version of xserver-xorg-video-ati: 1:6.14.0-0ubuntu4 (default in
  Natty). Same problems with the xorg-edgers PPA in Natty Beta2.

  The software affected: Compiz (doesn't start because requires direct
  rendering); then, Unity (just the wallpaper or black screen and the
  mouse pointer). glxgears, Stellarium, Blender, Adobe Flash Player in
  fullscreen mode and Visual module of Python work if software rendering
  is forced (but of course they run very very slow).

  The history of the bug: all worked as expected (out of the box) in
  10.04, but in 10.10 the problems started. The workaround was to
  disable KMS, but now, in Maverick, since the new Gallium driver
  doesn't have a non-KMS mode, that workaround is not available. This
  issue was reported when using 11.04 Beta 1 and Beta 2, then, in the
  descriptions below there are some strange things (xorg crash during
  startup, software rendering fallback), that don't occur any more. The
  issue is just the description given here.

  The exceptions: **sometimes** (??) the 3d acceleration does work as
  expected, but at the moment there is no way for us to know when it
  will work or not [help please!]. And, sometimes the 3d acceleration
  work but is so slow that it seems to be actually software rendering.

  The workarounds: `vblank_mode=0 glxgears` (or other program) gives
  correct 3d accelerated output. `export vblank_mode=0` also allows to
  start Compiz and 3d acceleration works after running that. That is
  just a workaround and the problem is not solved yet.

  [/edit]
  Binary package hint: xorg

  I installed Ubuntu 11.04 Beta 1, and I'm not able to run Unity and
  Compiz, because I have no 3d acceleration. However, I was able to run
  Compiz once, the next time I booted, I don't know why, Compiz doesn't
  work. After several reboots, I see the following:

  1. Sometimes (?), I have 3d acceleration via software rendering. When I run 
`glxinfo | grep render` I get:
  direct rendering: Yes
  OpenGL renderer string: Software Rasterizer
      GL_NV_conditional_render, GL_NV_depth_clamp, GL_NV_fragment_program,
  And if I run `compiz --replace`, I get the following error:

  2. Sometimes, I have direct 3d acceleration, but it's unusable.
  glxgears doesn't work (black window). Also, if I run compiz, I get a
  blank screen (no Unity, no windows, just the mouse pointer and the
  background image). In this case, if I run `glxinfo | grep render`, I
  get:

  direct rendering: Yes
  OpenGL renderer string: Gallium 0.4 on ATI RS690
      GL_NV_blend_square, GL_NV_conditional_render, GL_NV_light_max_exponent,

  So, I'm using the Gallium driver. I had a similar problem with
  Maverick and the radeon driver. I solved the problem turning off the
  Kernel Mode Setting (# echo options radeon modeset=0 > /etc/modprobe.d
  /radeon-kms.conf). I don't know how to do that with the Gallium
  driver. I want also to try using the radeon driver, but I don't know
  how to do it.
