Great.

/etc/pm/hooks/
seems to be a place that is like /etc/init.d but for suspend and resume
-- I guess the same for Hibernate. For example I have one guy in there
called "99resolution" I see:
#!/bin/sh
case "$1" in
thaw|resume)
{ /sbin/service 915resolution start ; } 2>/dev/null
;;
*)
;;
esac
exit $?
It's pretty clear that copying that into a file
"/etc/pm/hooks/50stophddclick" and replacing the { /sbin/service...null
part with
hdparm -B 192 /dev/sda
or 254 or whatever your magic number was would be a good bet for getting
run on resume or "thaw"... I guess that is specifically what it is run
with when coming out of hibernate.
