The problem seems to be totally oriented around the GUI. I use KDE, but havent applied the kde errata packages that I see on updates right now. And this definitely wouldn't explain why performance (as measured in GUI snappiness and general response times) improves when I boot back into the old kernel. This is an ATI Radeon 7500 with 16 MB, running at 1400x1050 and 24 bit depth. Was there any change in the X-related support stuff (DRI, whatever) in this errata kernel that could make a difference? For the moment, I'll stick with this - too many custom changes need to be made everytime I change kernels (winmodem driver rebuild, host_ap driver build, bunches of Thinkpad related modules, etc.). Maybe I should try fiddling with some hdparm settings and see what I come up with.
