Comment 45 for bug 30557

Dell Latitude D810 here.

This problem seems dramatically lessened but not altogether gone. Dragging windows and other video-intensive actions are marginally slower than with the -386 kernel. Also my screensavers now run at about 10% their regular speed. (ati binary driver) Yes, it's like watching a slideshow now.

I've been following this thread/problem for quite awhile, and hoped that this kernel update would solve all the problems. Looks like it's FAR better than it was, but things still aren't 'normal' vs. the -386 kernel.

I'd stick with the -386 kernel except that vmware is almost unusable with it; the -686 kernel is considerably faster.
