I have added some suspend/resume code to the latest patch (20080907 on

I am unable to test it completely due to lack of suspend support on my 
amd64 ACPI system. All I have tested now is the direct calls of 
suspend() and resume() on alive system which look like manage well with 
stopping and restarting devices.

Testers are welcome.
