Not at all.

I have X61s and X60s, both of which can suspend and resume. At least this
worked very well for the 6.X series, but for today's -current resume
occasionally hangs. Actually, not resuming itself (i.e., the system comes
back to life) but indeed the graphics (vesa) do not always resume. I have
no idea what causes this non-deterministic behavior, but vesa is a suspect.
I would also appreciate hints on how this could be even debugged.

I think after the big Intel/X.org/KMS/whatnot thing is resolved, it becomes
much easier to start more systematic investigations.
