I recently installed a PnP sound card. And after some help, a diff of my
kernel config (against generic) reveals only one significant line:

device pcm0 at isa? port ? tty irq 5 drq 1 flags 0x0

Note that "controller pnp0" is already present in the 3.2 generic.

So, look at pnpinfo, and right at the end is a list of actual
configurations. Mine looks like:

Logical device #0
IO:  0x0220 0x0000 0x0388 0x0000 0x0000 0x0000 0x0000 0x0000
IRQ 5 0
DMA 1 0
IO range check 0x00 activate 0x01

Now, I think pcm0 is clever enough to locate the port address itself,
but an older driver may need to explicitly specify 0x220. 

Sorry, this is the best I've got. Good luck.
