It causes hibernation to succeed <grin>.

I've attached a dmesg from a successful hibernation with both patches
applied.  And for comparison, a screenshot from a hung hibernation
without the fix, but with the debug patch you sent me.

[In both cases I tested directly on top of v2.6.33-rc6, i.e. no
changes to PAGES_FOR_IO or anything else].

Many thanks!
