[ltp] Is 3D possible on FireGL 5250?

[Phil Shotton]

I've grabbed the experimental packages Alex mentions below (see 
http://www.phoronix.com/forums/showthread.php?t=9951) and they seem to 
work fine. glxgears gives around 2,000 fps (was about 850 without 3d 
acceleration).

Haven't tried compiz or anything, but general use everything feels just 
a bit snappier. Suspend to ram works fine, but only if I undock first 
(this was also a problem with earlier driver and is probably nothing to 
do with the video drivers).

I'm still getting the occasional hang that I've reported before, but 
being careful with the docking seems to reduce the frequency. I'd 
definitely recommend the recent ati drivers, including the experimental 
mesa/drm 3d stuff.
