I'd look at what optimizations the march athlon-xp uses and compare that 
with the march you are going to there maybe some that you want to enable 
for the Core Duo. The CHOST shouldn't be an issue. It should be noted 
that you won't have an 64bit support if the new CPU even supports this 
don't remember off the top of my head. I suspect it will run without 
issues though.
