pnp devices are assigned unit numbers following legacy ISA ones (README...)
so pcm1 is correct. 0x328 is also correct since a PnP card has multiple
address ranges, corresponding in this case to SB emulation, WSS
emulation, synthesizer, midi, etc. etc.

as said above, all the ranges allocated to pcm1 are not used for pcm0

this is (probably) because I fail to initialize properly the IW chip on
the GUS. I need the help of some volunteer willing to backport the init code
in guspnpXX to my driver, and test it. Without the card it is terribly
hard to do something like this for me.
