I've been trying for awhile now to get the accelerated opengl renderer

guide alot: http://dri.freedesktop.org/wiki/ATIRadeon
I know it is important to change this string from glxinfo:
OpenGL renderer string: Software Rasterizer
to this:
OpenGL renderer string: Mesa DRI R200 (RV280 5C61) 20090101
x86/MMX+/3DNow!+/SSE TCL DRI2
But I'm not sure how.
It can't hurt to try putting it the "Device" section of xorg.conf, maybe
something like this:
Option "OpenGL renderer" "Mesa DRI R200....."
Xorg may spit in your eye, but it can't hurt to try.
This error in my xorg.log seems to be the key:
drmOpenDevice: node name is /dev/dri/card0
drmOpenDevice: open result is -1, (No such device)
By amazing coincidence, I just posted a similar problem to the xorg mail
list and got no replies. Maybe try some ATI lists instead?
Anyway, I finally got /dev/dri/card0 created at boot time by fiddling with
my kernel config a zillion times or two, and AFAICT there are two types of
changes that may (possibly) account for my success. I'm still not sure.
I finally got console framebuffer working by compiling support into the
kernel instead of as a module. In retrospect, the module obviously was
not being loaded at boot time when the card0 device should be created.
However, I also changed other kernel video/drm/fb support to compiled-in
instead of modules, so the console framebuffer thing may just be a red
herring. Try compiling all the video/dri/drm stuff into your kernel
instead of making them modules.
BTW, I added no udev support files for dri/card0, so that device is not
created by udev, apparently, but by the kernel directly.
