This affects the 'netbsd root on on xxx' kernel config functionality
as well (once we have this, RB_ASKNAME is trivial :)
Then this assume that the root fs has to be known from the bios (in i386
world, maybe this can be applied to other ports as well). 
You can't have your system on this biosless SCSI board and just boot from
floppy when you need to use it.
