I agree that this needs to be done a little more generic, and we want to
capsulate it in a seperate function.

This is not BIOS compatibility. It is broken OS compatibility.

In the specific grub2 case we could possibly fix this in the grub code
though,

term/i386/pc/serial.c: serial_hw_get_port (const unsigned short unit)
might indeed read the lbtable rather than 0x400 in case it is running on
LinuxBIOS.
