resource.c iotable_size too small (fwd)

When trying to add another 16 ports to our linux terminal server (for a
total of 64 serial ports), I ran into a problem : iotable_size in
resource.c is too small.

I increased the size to 80, which fixed the problem. From what I can
figure, this takes only 256 more bytes in the kernel (assuming the extra
iotable port space is unused). Is there any problem with making this

Also, given the limitation on ISA bus architecture, this seems a
reasonable limit to cover a fully loaded PC.
