Hurm. That's all well and good, I guess, but *why* is Linux initializing 
the on-board sound while FreeBSD is/can not? I admit my understanding of 
PC hardware to be limited, but I had thought that the purpose of the 
BIOS was to "initialize" the hardware for the OS to recognize. Doesn't 
it hand out IRQs and so forth?

Is my problem indicative of a general driver deficiency in FreeBSD?
Is there some module I'm not aware of that, were I to load it, take care 
of this mysterious "initialization"?
