In truth besides the Beowulf type application I would really like to
use linuxBIOS on my PC. So focusing on embedded solutions is

Maybe. I don't have any problem with building a board like that. I
just suspect that the development version of the board could benefit
from having a serial port. Maybe I just haven't written enough nic
drivers but doing a console over ethernet to debug RAM initialization
does not sound pretty :) And USB likewise. Anything that requires
DMA to use is not an appropriate interface for using before your RAM
is initialized.
The only thing I like about a serial console once a kernel is booted
is that it provides you with a redundant method of access to your
system. The other method being the network. I have had too many
problems with network drivers to really believe a single network
interface is a reliabel way to access a computer.
