Why not using a newer kernel?

Well, there are a few things behind the scene:
- ALSA developers have no BT hardware, thus there is no development
in this area
- snd-bt-sco is a wrong implementation
it just creates a bridge to a user daemon
- 2.6.14 kernel is too old for debugging and no worth unless someone
gets a support contract

How about bluez list?
