9.1.2 Postgres corruption, any way to recover?

Appears one of my bigger, but older DB's cored or other this morning and
when it came back up the DB shows that it can't start and is possibly
corrupted. I've read this was actually due to a kernel bug sometime back
(or at least tied to the kernel bug).

I'm wondering if there was any other work arounds or "tricks" that I may
try to recover, vs doing a restore from backup?

Not holding out hope, but maybe just maybe someone has some ideas/shortcuts
to maybe get this DB back up

Thanks
