I have been having some problems with getting RT_PREEMPT compiled for
my 52xx icecube board. Here is a patch that I created which compiles
for me. Just compiles and does not mean that the full RT_PREEMPT
functionality is available. :-)

However, PPC support for the CONFIG_RT_PREEMPT is currently broken and
I understand that the developers are working on this as we speak.

Prady
