By the way, it seems the PPC has instructions to do it.
>From the "PPC compiler writers guide":

Round Up or Down to Next Power of 2

The floor power of 2 ( flp2) and ceiling power of 2 ( clp2) functions
are similar to the floor and ceiling functions, respectively, but they
round to an integral power of 2, rather than to an integer.
