First, the 900A does not have built in bluetooth, and the default installation does not start dbus and bluetooth services 
properly.

To fix this go to /etc/fastservices and appended two lines 

dbus
bluetooth

The 900A is unable to find two key kernel modules:

/lib/modules/${DKERNEL_VERSION}/kernel/net/bluetooth/bluetooth.ko
/lib/modules/${DKERNEL_VERSION}/kernel/drivers/bluetooth/hci_usb.ko

They named incorrectly as bluetooth.2.6.21.4.ko and hci_usb.2.6.21.4.ko instead of the shorter names. 
Make symlinks to fix the problem and ran depmod -a to update the dependencies.
