hardware (as opposed to software/Mesa) acceleration.  the current=20
fglrx from Ubuntu loads and suspends/resumes, but I oculd never get=20
it to do hardware accel (which was the point of using it). =20
glxgears -> ~700 fps on Mesa, vs 3800 fps with hardware.

I'm assuming you meant 2.6.23 - what distro?  Ubuntu Gutsy only goes=20
to 2.6.22-14. I tried compiling a custom 2.6.23 kernel but as noted,=20
I never was able to tune it correctly (could you mail me out-of-band=20
your .config if you compiled it for a T60?)  What is the fglrx=20
version that worked?

in my debugging travels, I learned that AIGLX is supported in the=20
recent drivers; it doesn't need to be loaded.

I concur.  I'll buy Dell before I buy another laptop with an ATI card.
