I'd also add:

  - after suspend/resume - make sure DISK power saving settings don't change

ie.  on F8, I have to do:

  hdparm -B 255 /dev/sda

to eliminate the current 'click of ultimate demise' problem
with overly aggressive disk power management
(Unfortunately, I don't know where I can set-it/script-it
to run after a resume.)
