Patrick, 

It looks like your printer and soundcard are trying to share an irq. 
I'd be surprised if NetBSD were happy with that.

The gus man page says "The IRQ is software programmed, so you may
select any IRQ from the set {3,5,7,9,11,12,15}".  I take "software
programmed" to mean "settable with that MS-DOS binary they gave you",
so I guess you want to boot your not-so-favorite floppy, and
reconfigure the card for another IRQ.   

In the alternative, you may be able to redefine the motherboard's
parallel port as LPT2 (to use DOS nomenclature) through the BIOS. 
LPT2 uses IRQ 5, which would also solve the conflict.
