	Not having looked at the audio code at all, I would think that it might
make more more sense to have audio_attach_mi() defined to a noop if the 
audio* device isn't configured.  Or configuring an audio driver should
automatically pull in the minimum required code it needs.

	I ran into a similar problem when I tried to configure a kernel without
an isa device.  Even though there's nothing in the config file that attaches
"at isa?" things still use functions that are only pulled in when isa is
configured.
