It expects to be loaded with
insmod pas2 io=pas_io irq=pas_irq dma=pas_dma dma16=pas_dma16 sb_io= sb_irq= sb_dma= sb_dma16=...
Thats a fair mouthful and its sort of expected that tools like Red Hat
sndconfig will be handling it in distributions or folks will stick them
in conf.modules but it does mean a happier world for distributions and
folks who dont build kernels.
Anyway let me know if this diff works ..
