Yes, sorry, that is a change between the PCI code in 2.x and 3.x ...
It may be wrong to set those bits before calling the driver's attach()
and it most probably is too late afterwords. In case you are bitten by
the BM bit being set without your knowing, the error is hard to spot,
so I decided to no longer set the enable bits by default ...
