sco support in the form of integer encoding was merged by the gumstix people, however if you want to keep an eye on it then have a look at bluetooth-alsa on source forge for the latest details
A2DP can be done but requires streaming the music throgh a user space program, if your music player cat stream to stdout then you might have to redirect the file descriptor that sound comes out of with somthing like 3>1 or create a fifo with the player at one end and output redirected throgh that ( 3> /tmp/pipe)
hopefully it should be a kernel module soon without the need for the userspace app
