I don't know the answer to that, but maybe my story will inspire:

I have Dell I8200 with Radeon M9000 (R250) and got XFree86 4.3.0 running
with kernel 2.6. What I miss is 3D accelaration, and mouse is a bit
shaky for the first 10sec of X start.
I did not test the suspend (to RAM) yet, but I would not be surprised if
it won't recover because of graphical mode.

There is a nice patch for ATI cards for XFree86 4.3 (kernel-2.4)
concerning the 3D and suspend: http://cpbotha.net/dri_resume.html
Without this patch I could not do any proper resume with X on.

So overall, I need some more time to investigate kernel-2.6, maybe the
patch is applicable for kernel-2.6 too...

I guess you want to know whether the 3D accelaration is on?
The proper way to test is:
glxgears | grep direct
and perhaps install tuxracer - if the game is playable, 
then you have 3D accelaration :-)
