So I didn't do an lsmod while I was booted in to 'linux rescue',
however I did "dmesg|grep 3w" and saw the 3w-9xxx driver, and I could
see /dev/sda, sda1, and sda2.  When I ran lvm, it could see the
LogVol00 and LogVol01.  I did vgchange -a y, I think, and that added
VolGroup00-LogVol00 and VolGroup00-LogVol01 to /dev/mapper.  I was
never able to mount them though.  "mount -t ext3
/dev/mapper/VolGroup00-LogVol00 /mnt/sysimage" gave me an invalid
parameter, I think.  (I use tab-completion heavily, so I don't think I
mispelled anything.)

So this was my next thought.  I grabbed an Ubuntu disc and SysRescCD
(Gentoo based) but neither of them recognized the 3ware card, so I had
no sda1 to install grub to!


I'm sure I'll get this figured out eventually, and the fun won't stop
until then.
