[ale] acpi/apm/hibernate/suspend/et al

[Christopher Bergeron]

Can anyone shed any light on the conundrum that is hibernation/suspend 
to disk under linux?  My goal is to put my desktop machine into a sleep 
state such that I don't have to wait for the full boot process.  I've 
been reading up on swsusp, and I'm running kernel 2.5.67 (with 
suspend-to-disk [or is it hibernate]) built in. 

My questions are numerous - but specifically, should I use APM or ACPI 
for hibernat/suspend-to-disk?  Does it matter?  Is there a difference 
between suspend-to-disk and hibernate?  Does anyone on the list have a 
decent understanding of this and if so, could you shed a little light on 
the subject for us/me?

I've read the [outdated and scope limited] howto's, but I've found 
myself more confused than when I began...!

Does anyone have a current resource or any personal insight that can 
help provide a basica summary/overview of how I can do this (or the 
underlying technologies therein)?

Best regards (and much thanks!)
-CB
