Bluetooth driver is not closed, the source is in linux kernel. What is closed is the bluetooth firmware blob but that's pretty normal (see http://www.bluez.org/download.html for various firmwares) .

Audio could be replaced relatively easily, it is possible to access audio from ARM side and linux drivers exist or is possible to adapt them. Then DSP will simply sit unused. See linux port for Palm Tungsten T/T2 (OMAP 1510) for example, I think it uses same audio codec as 770.

wi-fi is a problem, see this mail for introduction
https://garage.maemo.org/pipermail/c...er/000001.html
basically there are two closed parts with open glue (=cx3110x.ko) between. To make it kernel-independent one needs to replace umac.ko module. As I understand it the firmware blob and the umac blob fit together so using some random open wi-fi stack with the firmware may be hard (just guessing).
