desktop apm (powerless sleep)

[Ben Luey <lueyb@gridley.ACNS.Carleton.edu>]

I was using a Sony Vio laptop and it has this great feature: you press a
button and it stores all your ram to the disk and cuts power. The laptop
is totally off and then when you turn it on it just copies the data from
the hard drive back to the ram and you are right back where you left off. 

Could I do this on a desktop with linux? Linux being totally stable but
taking a while to load seems like a great fit for this feature of desktop
machines. 

Thanks,

Ben
