I've edited the boot messages from my previous mail (the result of
fighting with pine over a slow link with a little too much coffee thrown
in), sorry to clog up the lines...
(fwd)
I've been trying to get my laptop sound to work with recent kernels.
It's a thinkpad 600e with a cs4610 on board. I contacted the author of
the newpcm code and he mentioned that instead of using the ac97 codec it
most likely uses a cs423x in association with the cs4610. This actually
jives with behavior I'd seen under openbsd and the older pnp code, where a
sound blaster was probed under freebsd, while openbsd and win95 both see a
window sound system lookalike. I'll note that I've never been able to get
anything but static out of the older freebsd and openbsd sound drivers on
this machine.
Anyways, the boot messages indicate that the pnp code for some reason
isn't getting any usefull info out of the 423x part (other than the midi
or synth part) on bootup (most of the other hardware looks like it
correctly responds to th PNPBIOS stuff)...
