Also, it turns out changing USB keyboards makes no difference.  I
don't think I have a PS/2 keyboard, anymore.  I've currently copied
all of my data from my SSD array to a HDD, and plan on trying to get
it to boot.  I've successfully ran mkinitcpio and grub-mkconfig from a
chroot on the HDD which did not return the error about not finding the
root filesystem, so I'm hopeful it will at least get me back up and
running.  I forgot to grub-install, though, so I'll have to wait until
I get home to test it.
