	this is needed when you have to compile serial driver built-in
	for serial console but have, for example, an IRDA device in one
	of the ports. In my notebook this happens and I'm unable to load
	nsc-ircc driver after that because the I/O range is already
	taken:
Serial: 8250/16550 driver $Revision: 1.90 $ 8 ports, IRQ sharing
disabled
ttyS0 at I/O 0x3f8 (irq = 4) is a 16550A
ttyS1 at I/O 0x2f8 (irq = 3) is a NS16550A
(...)
nsc-ircc, Found chip at base=0x02e
nsc-ircc, driver loaded (Dag Brattli)
nsc_ircc_open(), can't get iobase of 0x2f8
