This may be really really stupid, but for Mac minis that have no serial

ports listed in their dmesg (e.g:

http://erdelynet.com/tech/openbsd/openbsd-on-intel-mac-mini/) could you

use a USB-Serial adapter and place that directive in /etc/boot.conf to

redirect the console output? Nowt about that in boot.conf's man page:
set [varname [value]]

..

..

             tty      Active console device name (e.g., com0, com1, pc0).
I see that there are several mac mini colo outfits, such as
