I use 3/3's current with this patch on IBM TP X31. I can now successfully 
suspend/resume in X with dri enable on RADEON! (can't do that before, with
dri, after resume screen mess up). reset_video 0 or 1 both works. It even
works without vesa module loaded. The only problem is that my tracepoint
(psm0) dead after resume.

demsg (verbose) and suspend/resume dmesg are both
at http://rafan.infor.org/tmp/vesa/
