No to the wild card x.  Long experience has shown that manufacturers
almost never respect naming sequences so we simply name everything after
one supported part number.  It seems like a good idea, but we've been
bitten before.  

I'm fine with the _data to _state change but please combine with the previous
patch to void unnecessary churn where the same line gets updated twice.

These two changes are very closely related so fine to do them in one patch
in my opinion.
