Ok. Was a shot in the dark. I tried on a similar machine, but that one
resumes fine (except that the AHCI controller plays silly buggers, but
nothing interrupt related). I might have access to another core2duo machine
tomorrow.

I'll send you a debug patch shortly, but can you please first check when
the wreckage happens by testing the states in

    /sys/power/pm_test

freezer
devices
platform
processors
core

That might give some first hint to narrow down the issue.

Debug patch follows soon.

Thanks,
