Well, Seeing you asked...

PM resume certainly seems to be improving.
My main problem in rc1-mm3 is with PCMCIA.
If I stop cardmgr before suspend-to-RAM, and then try to
restart it after resume, I cannot.  Some message about the socket
being in use, and am I sure there is no other cardmgr running (there
isn't). 

I can stop and restart happily before suspending, but not after.
If I leave it running during a suspend/resume cycle it keeps working
but if I then stop and restart, it fails.

(and if I do leave it running, my PCMCIA wireless gets started before
my tg3 wired, so eth0 and eth1 get swapped).

I just tried rc2-mm1 and... decided to go back to rc1-mm3.

It seemed to boot mostly OK.  I tried suspend-to-RAM and it seems to
suspend.  But when I turned it back on again it rebooted rather than
resumed.

During boot I got:

I think those are the interesting processes, but I can get the full
list if it is useful.

I managed to proceed into the boot with alt-sysrq-E (tErm) but when it
came up enough bits had been killed that I decided to cut my losses
and go back to a previous working kernel...

This in on a Dell Lattitude D800
