Testing this now (2.6.36-rc4-tp42-suspend-next-vmembase-0-00253-gab9b069-
dirty).
So far so fast:

The read ahead patches bring a pretty nice performance upgrade ;).
I wonder a bit about:
Oct 1 11:26:19 shambhala kernel: PM: Image written at 18 MB/s.
This has been without read ahead patches which shouldn't interfere with
