Hi All,
Well its all back to normal! By mounting devfs to the new virtual
chroot area I was able to complete a buildworld/installworld of the current
branch, after a reboot the system came right back up with all my old
services started normally.
Thanks,
-Jason

I would boot with the 5.1 live CD and backup all the data you want to
save somewhere (like to another machine), then I would reinstall the
system from scratch with the release you intend to run, wiping the disks
completely. Then restore the data you wanted to keep from whereever you
saved it.
If you have a lot of data and a reasonably fast network link and no
place to temporarily backup your data too while reinstalling, I can
provide you with a temporary account with lots of disk space for a few
days. EMail me privately if you need the temporary account.
