There was a previous patch IIRC by Dan Parrot to which again IIRC
ronald objected due to use of intrinsics instead of hand written asm.

I did not entirely agree with ronald though i always saw his point and id
like to hear his oppinion on this patchset. Also i dont have a working ppc 
with which i could test this ATM.

So to move forward what we need is
1. ronalds oppinion
2. someone with the right hardware needs to test and confirm both
that this is faster and that it works correctly
3. simple code review

If these 3 pass, my oppinion is that its an improvment and it could be
applied.

thx
