I also tried 2.6.25-rc5 from http://kernel-archive.buildserver.net
/debian-kernel/ and the problem is present.
Changes between 2.6.25-rc5 and 2.6.25-rc6 solve the problem.
The changelog of 2.6.25-rc6 talks about the problem with the nosavepage:

Hibernation: Fix mark_nosave_pages()
There is a problem in the hibernation code that triggers on some NUMA
systems on which pfn_valid() returns 'true' for some PFNs that don't
belong to any zone. Namely, there is a BUG_ON() in
memory_bm_find_bit() that triggers for PFNs not belonging to any
zone and passing the pfn_valid() test. On the affected systems it
triggers when we mark PFNs reported by the platform as not saveable,
because the PFNs in question belong to a region mapped directly using
iorepam() (i.e. the ACPI data area) and they pass the pfn_valid()
test.
Modify memory_bm_find_bit() so that it returns an error if given PFN
doesn't belong to any zone instead of crashing the kernel and ignore
the result returned by it in mark_nosave_pages(), while marking the
"nosave" memory regions.
This doesn't affect the hibernation functionality, as we won't touch
the PFNs in question anyway.

I'm unable to know if it's just specific or if lots of changes in the
kernel resolve the problem.
