There is a better way. Copy the correct code for printing d_port and
d_portn from isa_devtab() to isa_biotab(), and while your're there,
check for other lossage in isa_biotab(). The current code also screws
up cases where the token following "port" is a number. Only the case
where it is a macro name works.
