there's a kernel patch in snd-bt-sco, and it would  be great if someone
could explain what it does:

Also, it would be interesting to know if this patch for kernel 2.6.4 is
still nessesary for newer kernels (2.6.6 to be specific), because I want
to "port" snd-bt-sco to alsa 1.0.4 and kernel 2.6.6.

thanks in advance,
