3.2-stable review patch. If anyone has any objections, please let me know.
------------------
From: Malcolm Priestley <tvbox...@gmail.com>
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.
