That's my plan...

Sure, I guess so -- nothing should break if the MAD layer does this
(since the driver can't remember that it already saw the MAD).  But
when do you see this being done?  If the driver didn't handle the MAD
the first time around, it's unlikely to do anything different on the
second try (unless the MAD layer does something extreme like change
the attribute ID, and I can't think of a time when we'd do something
like that).
