[wplug] Desktop Sleep?

[J Aaron Farr]

Hello all.

I've got a Sony VAIO desktop that dual boots WinXP and RedHat 8.0. 
WinXP can somehow control the fan so that it's not always running. 
Additionally, there's a way to send the computer into 'sleep' mode, like
you would for a notebook.  Does anyone know of a way to do this in
Linux?  Is there some special kernal patch that I can compile that would
add this sort of feature?

Thanks,
jaaron
