Jeff,
I took a stab at it and got it to boot, but the boot hung around rc.local.
So I rebooted it with init=/bin/sh and manipulated it a bit by hand.
I have three drives in the machine:
ata1: sda: spare disk that I test Andi's RAID1 theory.
ata3: sdb: first drive of the system RAID1 pair
ata4: sdc: second drive of the system RAID1 pair.
I can write to ata1 no problem; I did the following:
cd /
mount /dev/sda1 /mnt
cp -axv . /mnt/root
sync
and that all worked.
Can't seem to write to ata4:
ata4: command 0x35 timeout, stat 0x50
ata4: command 0x35 timeout, stat 0x50
ata4: command 0x35 timeout, stat 0x50
/proc/mdstat shows:

I'm heading home now (it's 22:00, and I've been here 16 hours already), but
I figured that I'd post what I have thus far, and perhaps you can tell me
what the problem is.
