Hello.

I've tested both  mainline and http://cgit.freedesktop.org/nouveau/linux-2.6/

mainline - commit fe0d42203cb5616eeff68b14576a0f7e2dd56625 ("Linux 3.0-rc6")
nouveau-2.6 - commit 72690683e35680d912e9b8ff2ee0b7a18631dd0d ("drm/nouveau/pm:
Document and expose CL and WR for 0x1002Cx")

doing echo mem > /sys/power/sleep send my system to sleep, but on resume i can
see only blank vt, if i run this command from console. I can poweroff machine
via ctrl-alt-del, or power button. If I start X, and suspend from xterminal -
on restore i can see X again, and work as usual, but non-X VTs still blank
(with small line-shaped cursor in top-left corner).
