Gambol, I have the exact same problem? Did you get it resolved?
I have a similar question at tonymacx86.com and it has been confirmed that the Apple wireless keyboard DOES work in Chameleon... which means the issue is related to BIOS settings or BT dongle used. I use a Gigabyte mobo (P55A-UD3) and an AZIO BTD211 bluetooth dongle. The Belkin F8T016 dongle is reported to work.
If you got this to work what did you do to fix it?
Thanks in advance.
