If BT HID driver does not work with the Xbox BT control, then lets assume no hope for a driver. (Doubt its very simple to write drivers)
Anyone up for an obscure idea?
How about a very simple program that would output based on input?
So...
BT or IR keyboard sends A to the PPC to be interpreted as A in the hypothetical utility. The utility then uses what you have setup to connect A with say x0C1 [think morphgear gives stuff like that when binding a hardware key] Add options for holding or repeating and maybe we will get greater compatability.
(Full of ideas, 0 programming skills)

Reply to my question to hipgear:
The LM616 is only compatible with the Xbox. We are just starting to explore options for future Bluetooth devices so maybe someday soon you will be pleasantly surprised.
