I can add that on my laptop (toshiba U305, Intel 945GM chipset), s2ram -f -p -m which used to work ok, in X and console, in 2.6.24 stopped to work (I tested -rc8, but I think it's like that since a long time). Machine resumes but the screen stays off after that, although machine is working (exactly as Soeren said). On the other hand, now the plain "echo mem > /sys/power/state" works perfectly, from X and console. So some of the magic vbe save/restore of s2ram mess something up for this card. Is it a regression for my laptop (is evidently one for Soeren)? On one side, a "used to work" setup is broken, but it worked with userspace hacks; now it works with the plain way, and that's clearly better. I added on Cc: Jesse, to whom I confirmed that Intel suspend/resume was ok on Feb, 21, [1] and suspend-devel list, because now I do not know what to do with the whitelist I sent for s2ram for this machine...
