Jeff, for the hang on suspend problem, I know suspect something else in 2.6.25-rc2 caused that. Can you try the 2.6.25-rc1 version of i915_drv.c (in fact all of drivers/char/drm from 2.6.25-rc1) but in a 2.6.25-rc2 kernel? I ask because 2.6.25-rc1 suspends to disk just fine for me and resumes w/o a green screen, while 2.6.25-rc2 fails to suspend (hangs like you say) and gives me a green screen. Were there other changes in ACPI or the PM core that might have caused this I wonder?
