I want to make all machines, including old ones, work :-) Restoring the behavior of incrementing the base address for HP interfaces *might* fix an old machine that has been broken since mid 2006 (when b0defcdbd2b7d went in), but we *know* it would break current machines. At this point, I think the only real option is to preserve the behavior we've had since mid 2006 and fix old machines if and when we discover them.
