If anything, this patch made my display flicker even worse than
without it. Frame rates seem slightly lower, but glxgears gets around
1450-1500fps at only about 50% CPU (vs 1500-1600fps and 100% CPU
utilisation without the patch).
This is at 24bpp. Because @ 32bpp in xorg.conf, X doesn't start
(Unsupported bit depth is the error).
I also tried 1024x768 resolution. Same thing. (In fact tuxracer runs
at a lower res I think. Hard to tell, I have the default screen
expansion turned on for the LCD. Must turn it off).
Alex. Are the databooks still a dire secret? Or can you share (If
softcopy). Or can ordinary mortals get hold of them?

Hamish.
