It's great, that Tekram makes driver sources available, but in fact, I 
guess, we got the more efficient driver in our source tree ;-)

Tekram's drivers use a common layer for their AMD and NCR based cards,
and that implies, that they use the processor in the NCR SCSI chip just 
as an advanced DMA unit with scatter/gather support.

The Tekram driver has not been ported to 3.0 (i.e. does not work with 
CAM), so you don't have much of a choice, unless you stay at 2.2-stable.
