Interestingly, a PCMCIA serial card which hadn't worked before is
working now.

	% uname -a
	NetBSD oratosquilla.PLALA-ADSL 2.0G NetBSD 2.0G (LIBRETTOL2) #10: Wed Sep  8 22:51:30 JST 2004 i386
	% dmesg | grep com0
	com0 at pcmcia0 function 0: <Socket Communications Inc, Serial Port Adapter Revision B, ^Z^E^A, >
	com0: ns16550a, working fifo

I haven't looked into which changes made what, but this shows that the
current code is not totally broken.
