Some hacks to the configure script may be needed before cross compiling 
is possible. I have not done this yet because I don't have any 
environment wehere I could test it.

You can put the INB/OUTB/etc macros (and the inline asm routines above 
them) inside an #ifdef i386/#endif block. Then define these macros for 
Mips. The __inb/etc routines are identical to the inb/etc routines used 
in Linux. You can copy the mips specific macros from asm-mips.


What kind of audio device you use?
