The standard way of doing this is to do two commands:

1) INSERT without the REPLACE
2) UPDATE

When step 1 fails because the key values already exist you trap this and 
explicitly ignore it in your code (commented, because you're being nice to 
other programmers).  Then it's always the UPDATE which updates the fields you 
care about.
