Blech, not going to be fun to fix this sucker.

It didn't bring it back, but I'm also not at home to look at the
device either.  Bummers.  I'll play around with this some more and get
back to people when I can.

Should I be moving back to 2.6.13-rc6 to get the speedup on /dev/sda
anyway?  Since my OS partitions are on SCSI.
