I've started with bc75d33f0 (one commit before d239171e4 in Linus' tree) but then my system fails to resume. Whatever I do (change fb/Xorg drivers, disable X, etc.) I always end up with unusable display and something that looks like hard-locked system (I haven't tested network connectivity from another box, but console is surely dead). Thanks.
