I'm afraid 2.0 currently has no support for either APM or ACPI
power management. All bets are off when you shut the lid :-(

The roadmap for 2.1/3.0 has us heading in the right direction
with making more of this stuff visible to domain 0 so we can use
the existing Linux code. 

For the moment, it mightn't be too hard to hack software
suspend/resume to do the right thing...
