At this point does an 'lsmod' give any further clues?  For instance is
the LiveCD using the same driver for the RAID you are expecting to use
after the reboot?

I'm quite prepared to be entirely wrong.   It's been years since I
installed to a PERC, and I believe it was a PERC4 when I last tried, but
I seem to remember being offered all of the physical disks as separate
drives.

Let's continue assuming I'm incorrect and you should be seeing just a
single logical drive.

Looks good for a battery backed RAID card.  Although you've been
referring to /dev/sdb3 in your mail.

Is that the correct total size of the logical drive, or of one of the
physical drives?

Ouch!  Something is very wrong here.  I don't think you're going much
further until this one gets fixed.

Are you sure you're running the same driver for the card as was used
during the install?

Maybe you could try using genkernel to build the kernel, which will also
create an initrd to autoload most needed modules just like the LiveCD.

Also, I doubt if this is necessary with a hardware RAID controller, but
perhaps emerge'ing device-mapper is necessary.   Perhaps also mdadm too,
but I'm even more doubtful about that one.

Cheers,
  Steve.
