Yeah, I've been swinging at it, but I haven't had much luck yet.
I have one change which allows the X screen to come up, but hang after a few
jiggles of the mouse cursor.
.. I haven't got farther, but I haven't really had time to look at things
this week anyway...
The real problem is that we have no idea what sort of crazy programming
needs to be done to properly setup card for 3D. I do have the FGLX
8.2.48driver working, so I have hope that the 200M can be supported in
an open
source driver.
We need to figure out how FGLX is configuring the driver.
I have some crazy ideas like running the Xorg in valgrind and catching all
of the memory writes to the video registers. However, that still won't get
me the setup which the DRM kernel module is doing. (NOTE: This trick might
be usefull when trying to figure out how the card is issuing OpenGL
commands, but there are other tricks that work for that, too.
The best we can do for that is let the FGLRX setup the card, and then try to
read the registers that might be important. After we have those values, we
can try to figure out which the opensource driver is getting wrong.
I have some scripts that pull some values, but I have no idea if they are
the important ones or the ones that need to be changed.
(Alternately, we could have someone disassemble/decompile the FGLRX DRM
driver, write a spec, and then have somebody else properly implement a
driver from the spec. Kinda like people did for the broadcom wireless card:
http://bcm-specs.sipsolutions.net/ However, I don't want to do that myself
as it might mean I couldn't submit the code to Xorg in the future.)
Cheers,

You should drop Phillip Ezolt a line, as he has been trying to debug the
issue. You can reach him thru this list or [EMAIL PROTECTED]
