Hello,

On a rather generic ECS motherboard with an AMD processor (64 bit capable, 
but I'm running i386), I'm seeing strange port configurations. This is 
with NetBSD-4 from yesterday:

com3 at acpi0 (PNP0501-1)
com3: io 0x3f8-0x3ff irq 4
com3: ns16550a, working fifo
lpt3 at acpi0 (PNP0401-1)
lpt3: io 0x378-0x37f,0x778-0x77b irq 7 drq 3

There are no other com or lpt ports.

Normally, I wouldn't care what the "com" number is, because it always 
starts at tty00. However, I can't use tty00 - my serial port shows up as 
tty03. 0x3f8 has always been the first com port...

Is this a bug? An accident? A "feature"?
