In fact, guess 1 is irrelevant. :-)

This is a famous problem, just look at vt.c, you'll see a lot of ifdefs
around sound routines. Just every porting engineer who encounter this
problem solved it himself (and added own ifdef to vt.c). In my case, I
just got fault epc, found the address in objdump -D output and look at
the sources. For me it seems easier, than posting a message to a list.
