Is there any OS that can store the state on the H/d? I would've thought this would be incredibly 
difficult, as you'd have to store everything including CPU registers, peripheral state, PCI/AGP/ISA 
processor state (??) etc and then do a memory dump (writing to disk, thus altering the system state)... 
sounds like something the hardware would have to do...

I think APM already does...
