I was kind of thinking this might be a red herring, but, unfortunately,
the change was done at the same time as the other change. So much for
the good scientific principle of changing one variable at a time.

I don't think it ever was written to properly from install, and grub-
install didn't work period until I made the two aforementioned changes.

I do see the 3Ware BIOS at boot. Trouble is once the box has booted, no
love.

I'll poke around some more manana.

See above. Card is seen during POST.

Yeppers. No love.
