Yes, I've compiled BlueZ for our devboards using a BT USB Dongle with the PAN Profile. To enable support in your
kernel you need to add the following line in arch/cris/config.in to allow BlueZ to be configured:
Run make menuconfig and enable the features you want, currently I've only tried the USB stuff.
For the applications you need to modify the Makefiles for the BlueZ-packages to allow it to
compile for the cris-architecture. I'll send you the applications in a separate mail.
