Running kernel 2.6.0-test7 with patch #706 (compiled in atm, but no speed diff)
Running XFree86 4.3.99-14 with patch #723 (installed with make World && su -c
"make install"; XFree86 -version gets proper one though)

I can get DRI working (tuxracer works great, glxgears up to ~200, nwn ~3fps
tops).  Glxgears without dri are about ~180-220, but CPU usage makes it obvious
that dri does in fact work in the former case.  Preemtive option in the kernel
makes no difference.

At one point in the past, I had X saying that dri was enabled in my logs and
glxinfo claiming it was not (should be unrelated to this though).  This line in
particular I think might indicate the problem, but most references refered to it
as a 2D problem: "(WW) RADEON(0): Failed to set up write-combining range
(0xe0000000,0x4000000)".  Also, I get a "disabling TCL support" in whatever
terminal I try to run an app that uses OpenGL.  KDE also crashes near the end of
it's startup, so I'm using IceWM atm (noticed that this seems to be kernel
dependant behavior but not yet narrowed down the cause).

The base distro I started with is Mandrake 9.2 download edition.  The hardware
is a Compaq 2100 series (AMD Mobile 2200+, 512MB ram, 320M graphics).

suspect unrelated, but still curious

In /var/log/XFree86.0.log, I get some of these.  Anyone know offhand how to
disable this check?  My hardware does not support APM.
