	I actually tried hw.pci.allow_unsupported_io_range = 1 to no avail.  I've tried building pcm into my kernel, I've tried loading them as modules with no success.  I was reading somewhere that I may need hw.pci.enable_io_modes = 1 to use my sound card.  However I cannot boot unless I set hw.pci.enable_io_modes = 0.  Any ideas on how I can get around this?  Or if this will even help...

Thanks,
