Worked fine yesterday. I switched to alsa modules aka alsa-driver.
snd-bt-sco modprobe loads fine
I even compiled the emu10k1, which has a function that is used.

fwiw, the nokia 770 guys came up with a cleaner way to get the hwdep
stuff built.

explain what you mean here. as opposed to compiling everything directly
into the kernel?

you mean the new alsa driver inside btsco? it's not working yet and it
shouldn't be causing any problems.

OK I am certain now. bluetooth-alsa cant work when using alsa-driver.
Even when SND_HWDEP is included.
I cant use BT-alsa when I compile alsa as modules in the kernel.
I dont understand the difference.
Is it to do with new alsa-driver ?
