the gdb debugging piggybacks onto the ddb debugger
the file i386/i386/i386-gdbstub.c gives the basic
interface for the serial connection.
the serial part is in /sys/dev/sio/sio.c
I don't know what gdb does on the ethernet but my guess is that it's
already written there somewhere.
I guess using udp packets with an address set by a sysctl
would be sufficient,
especially if we had our own udp handler (which I'm told can be done in a
very small amount of code it we know what packets we are getting).
