Nils,

About the power issues - you are right I do have higher power usage 
after a resume ;-) .

I tried your fake X server trick, and it seems to help with maybe 2-3 
watts difference, but still there is something going on here.
Also, I had to do that before restoring vbestate, not just before 
switching vt's, or I would get display corruption.

Are you having still this couple of watts difference?  Hows this sound - 
I got this vbestate stuff down so you get the power issues solved and 
we'll be even :).
