I've now bisected this to this commit:

http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commit;h=9cd9a0058dd35268b24fa16795a92c800f4086d4

If I revert that from 2.6.24 hibernation also works with it. With 2.6.28 the patch does not cleanly apply so I didn't test it.

I am able and willing to test any patches you might cook up.

Thanks!
