Do you see interrupts when reading or writing to /dev/audio?
The cardbus problem looks a bit like missing interrupts as well - you  
should at the very least see an interrupt when inserting a card, even  
if it doesn't attach.
Leaves the question what could cause /that/ - as far as I can see you  
have a bog standard UniNorth OpenPIC which works just fine in  
countless other machines. Wouldn't be the first time that Apple at  
some point introduced variants that need special handling somewhere.

Something completely different - a fairly recent ofwboot.xcf ( from  
5.99.29 ) Just Works(tm) on my beige G3 ( with OF patches from an OSX  
CD it would happily boot a NetBSD install CD ), to my utter surprise.  
These machines had to be installed via floppy or network thanks to OF  
bugs.

have fun
Michael
