Not in this case, cause i compiled everything into the kernel.

119 entries.

Nope, not there.  But for this kernel i intentionally left it out.  I
shouldn't need that, right?

i don't have any wavs to test.  just alot of mp3s and assorted movie

yea, i've gone through that a few times, but it seems to assume that i

since alot of it talks about the APIs present in 2.4.x
