61240ae556 fix chroma mc2 bug, this is based on a patch by (Oleg Metelitsa oleg hitron co kr) 
and does slow the mc2 chroma put down, avg interrestingly seems unaffected speedwise on duron
this of course should be rather done in a way which doesnt slow it down but its better a few %
slower but correct then incorrect
