I was unfortunate enough to end up with one of these chips in my laptop and am
wondering what, if anything, I can look forward to. A brief synopsis of my experience:
The only X-included driver that will work is the generic VESA driver, which helps me
not. Have compiled DRI and as usual, the RADEON driver causes X to crash with a no
devices error. So I force chip detection with:
Driver "radeon"
ChipID 0x4966
Option "AGPMode" "4"
Option "noaccel"
VideoRam 65536
This works, but again, gives me no improvement over the VESA driver, as it is the
acceleration I am seeking. If I comment out the Option "noaccel" line or chage it to
Option "accel", X starts, but the top half of the screen is blank while the bottom
shows the desktop background. Mouse and keyboard lock up. This is the X log, beginning
before the errors:

Not knowing the current state of affairs, I emailed [EMAIL PROTECTED] severl days ago,
very nicely requesting that they either release the specs for this chip to DRI, Xi
Graphics, and/or XFree86 OR develop their own proprietary drivers. Of course, I have
not received a response.
My questions: Has ATI been forthcoming with documentation for this chip? Either way,
is there any active work being done on a driver for this chip? If not by DRI, does
anyone here know of any work anywhere that is being done on Linuyx support for this
chip? Is it simply an issue of writing device drivers or does there need to be some
type of kernel-level support for the device? If no work is being done, is it merely
due to lack of documentation by ATI? And finally, regardless of any of the answers to
the above questions, may I remain hopeful regarding support of this chip in Linux?
Thank you all for your hard work and for reading this post! I thank you in advace for
your responses!
