One more odd thing I noticed:
With ad0 attached like as before this problem occurred I correctly see
this at the loader:
F1 FreeBSD
F5 Drive 1

Drive 1 is a raid array on another controller.

With ad0 disconnected and da0 being the boot drive I only see:
F1 FreeBSD

Considering that doing a make work && kernel with a ad0(which I guess
BIOS will see as the new drive 0) attached after the initial system
installation on da0 rendered booting from
da0 unusable, I think something very wrong must be happening.
The disk to consider writing any new boot information should be the
one where / lives in, not disk 0 reported by the BIOS. Well, that's my
view of it anyway...

I'm really unable to restore booting capabilities to da0 so any hints
are highly appreciated.
