Hm, so looks like I'm not seeing some ghosts on mine either. 2.6.25-rc8
xorg runs under etch, but enters a tight (no syscalls) loop woth 100% CPU
load under lenny. A 2.6.24 based kernel works under both etch and lenny...
Haven't had time to try to localize the problem. Glint xorg driver, DRM
and AGP are off, CONFIG_FB_PM2=y.
