"depends".  the aic7770 (the chip on the 2940) is perhaps a 
slightly more gutsy device than the 53c810.

No, they are totally and utterly different.

The FreeBSD community _IS_ behind it, for crying out loud.  The NCR driver
is perfectly functional, and only loses to the aic7770 driver at the
high end because of basic hardware limitations.  I have no problems 
keeping 2 or 3 spindles quite busy with one, and given the $2-300 price
difference here, that makes me a happy camper.

Have you ever tried an NCR-based controller?
