The only reason for using  ppc64 userspace apps is to access more than
4GB memory.
ppc64 binaries are slower than ppc ones due to the higher memory
footprint (thats not the same as x86_64 where you get more registers).
But if compiz works on pcc64 its ok to have it there (like we do for
all other packages).
And while building compiz-fusion for ppc64 I spotted a real bug and
fixed it (fix is also commited upstream now).
So it does not hurt ;)
