Sorry, I forgot you need pm-utils 1.1.2.4-1ubuntu8 from
intrepid-proposed for that to have effect. Please test. pm-suspend has a
few backends that it uses, which are tuxonice, kernel, and uswsusp. If
uswsusp is selected, as of ubuntu8, it'll use s2ram if found, otherwise
it'll use the kernel backend for suspend and s2disk for hibernate.

So yeah HAL supports only pm-utils, but pm-utils supports uswsusp,
kernel, and tuxonice. Don't bypass it.
