Powerhooks don't get run on S1 (standby).. maybe we should run them. I'm 
working on fixing them to survive an S3, currently (uhci/ehci don't work 
very well afterwords).

This means your BIOS doesn't support the S3 state. The error message 
should probably be made more clear.

Does your system (apart from uhci) recover properly from S1? If so, I'd 
say that's working fine for you. I'll check the acpidump output to see if 
your system is supposed to support S3.
