Owners of Acer Travelmate 60X told > me that the video doesn't come back. But in the these case the whole system > locked up on resume, so we can't tell if the video resume works. it also happends for the 80x series (in my case 801Lcib) with ATI Technologies Inc Radeon R250 Lf [Radeon Mobility 9000] using the framebuffer. "echo 3 > /proc/acpi/sleep" and "echo 4 > /proc/acpi/sleep" doesn't work because video doesn't come back as described by Stefan. The only reaction is the fan which runs like hell and doesn't stop. Same thing with pmdisk and suspend to disk ("echo -n disk > /sys/power/state"). All tested with recent kernels 2.6.7-2.6.8-rc3 . But with swsusp2 as the suspend to disk system ("echo > /proc/swsusp/activate" ) on a 2.6.7 kernel the video card recovers!?! I don't know much about the whole thing and why swsusp2 can (help) recover(s) the video card but perhaps it may help you.
