Not really, because it means the 6120 chips would not work,
and the new 7220 still works better with MSI.

I don't think the config mechanism can handle that as it stands
unless we created a different driver.  Or have I missed something
that would cover that issue?

The number of systems without MSI keeps dropping, so I think it's best
to leave it as is.
