There are a couple of issues here. First, for historical reasons which
I won't go into for fear of hurting feelings, the defaults used by the
SB16 driver bear no relation to the defaults on a card when you take
it out the box, so it's almost always a mistake to not specify the IRQ
and DMA in plan9.ini; for example, the default driver IRQ is 7 which
will clash with the lpt IRQ. The plan9.ini configuration for an SB16
with default hardware settings should be something like

	audio0=type=sb16 port=0x220 irq=5 dma=1

Secondly, the SB16 doesn't show up in the iomap output because the driver
doesn't call the routine to register the space it uses. That's a bug we
should fix but shouldn't affect the operation of the driver (assuming there
is no actual clash with another device).
