It does have a console redirection feature, in fact, and I had to disable it
for the same reason.  It is possible that there is some interaction there.
I tried it in several configurations, and I didn't take notes, but I think
that I made one attempt with the BIOS console redirection disabled but with
GRUB still installed.  I cannot take the server down again to test this,
unfortunately.

If you are confident that GRUB is behaving correctly in this respect, I am
comfortable blaming the BIOS and this bug can be closed.
