Hi Carlos,

I've merged your patch, in the Development tree, with some modifications:
- I kept the compat list for fentonups models. I'll wait for users feedback
to switch these to megatec, as I think there are important calculation data
declared in fentonups, which are not present in megatec (or am I wrong?)
- I've switched all the remaining compat list references from powermust
to megatec (ie Soyntec, ...)
- I've kept the powermust removal. Other drivers will be removed, during the
Development process, but only when we'll be sure that the support with
megatec is fine (a call to users on -dev, and possibly on -users will be

I really like the superdriver (what I call Meta driver is the same).
This is the long approach we have to have (see my QA tasks note on that

There is some work to be done, but calling for drivers authors and users
will help a lot...
