Take this, and make it happy on Debian. 8^) Buried in it's RH
innards is the gunk that they use to kill sound on suspend, and
restart it on resume. (Even kills programs and restarts them.) I've
never gotten around to ripping out the sound parts and making them
work on Debian, but you're welcome to.

# for a start and definitely enough for most laptops we have two links and
# according subroutines defined here: suspend and resume; all other links

# suspend and resume call apmscript, so you can also do other things (like
# reinitialising some PCMCIA-Card) there; apmcontinue will get the name
