3.7-stable review patch. If anyone has any objections, please let me know.

commit ab1dd9963137a1e122004d5378a581bf16ae9bc8 upstream.
Calling RFbSetPower with uCH zero value will cause out of bound array reference.
This causes 64 bit kernels to oops on boot.
Note: Driver does not function on 64 bit kernels and should be blacklisted on them.
