Can you try with the patch from
http://bugzilla.kernel.org/show_bug.cgi?id=11178#c10
please?

Well- I can suspend now! Make sure that patch goes in for sure!

... but the resume fails. It doesn't seem to see the signature in the
swapspace and begins a regular boot. Let me make sure it's not something
on my end.

The kernel command-line (and boot kernel) is exactly the same when
resuming, right? (Hmmm ... do I explicitly need a "resume=" parameter?)

It's better to always put the resume= parameter into the kernel command line
if you use the /sys/power/state interface.

Doh! Explicitly setting the "resume" parameter fixed the resume issue
(which, co-incidentally is what I'd pulled out for testing :)

The patch is on its way to Linus, AFAICS.
