I guess it all depends on what you use it for. Personally, I am not very
interested in suspend/resume but I sometimes use an external 1280x1024 LCD
and sometimes the 1400x1050 in my T42p. This new ATI driver is the first
from either ATI or xorg that correctly identifies and sets the resolution
for whichever one I am using at the time. And, the current xorg driver
(6.9 beta/rc) whether from Mandriva cooker or self-compiled always gives
me a hard lock up with no error messages or anything else to figure out
why.
