Tested with rc3 (rc2 wouldn't compile), and it works fine.

If you're willing, please add

Signed-off-by: Nigel Cunningham <ncunning@...hat.com>

or

Acked-by: Nigel Cunningham <ncunning@...hat.com>

to the hibernation related parts as you see appropriate, since I helped
(albeit in a minor way compared to your work and Eric's work) with
preparing and testing them for RHEL5 and have confirmed they're still ok
in this version.

Regards,

Nigel
