Thanks.  I poked around and only found a per-bus flag rather than 
one per board.

I checked various drivers.  Most of them turn it on.  It looks like 
the same chunk of code was copied around. 

I was going to ask where that code was for the Tulip driver.  I couldn't 
find it.  Suprise.  It doesn't work either.
