What a pity you never read the tip in the Boot+Root+Raid+LILO HOWTO that
I referred to upthread:

# BIOS=line -- if your bios is smart enough (most are not) to detect
that that the first disk is missing or failed and will automatically
boot from the second disk, then bios=81 would be the appropriate
entry here. This is more common with SCSI bios than IDE bios. I
simply plan on relocating the drive so it will replace the dead
drive C: in the event of failure of the primary boot drive.

That _seems_ to address the exact situation you speak of. I haven't
tested this, but I might eventually get around to doing a test.
(My systems currently use GRUB 0.9x, and my present intention is to
migrate not back to LILO but rather to extlinux.)
