Thanks ;).

There are some other subtle differences (in dmaintr routine, match, attachment 
code), but these could be merged very easily. 

I though about merging similar drivers for 53C710-based controllers into one. 
But I'm hesitant to touch a driver I can't test. That's why I created a new 
driver. Anyone on this list owns Warp Engine? A4091?

Yes, only BPPC with SN Ixx-xxxx has SCSI.

Ok, later today I'll prepare a new version which does this. Should be trivial.
