Er, how do I suspend without tuxonice? I've never used the in-tree swsusp
successfully (last time I tried I didn't just get a crash but massive
filesystem corruption, so I sort of haven't dared: reporting it would have
meant reproducing it, and I didn't want to touch it with a bargepole after
*that*).

Ideal would be a way to kick off the freezer and then just unfreeze without
suspending: that'd be pretty much risk-free...

It's kind of strange given that quite a few people use it daily, including
everyone using hibernation in the default openSUSE setup.

Anyway,

# echo core > /sys/power/pm_test
# echo disk > /sys/power/state

should do the trick.
