Please allow me to add two comments:

1) Did you try a DC390F under FreeBSD-current, recently :)

2) Tekram offers (BSD copyrighted!) driver sources for their cards, 
   including the AMD 53c974 based ones. See their Web page (sorry, 
   don't remember the URL, but there was an announcement in a FreeBSD 
   list, a few weeks ago). But those AMD chips are far less capable 
   than the NCR chips!

If you are looking for a good NCR based card, then the Tekram DC390U
(with an Ultra-20 8 bit SCSI bus) and the DC390F (Ultra-WIDE), both 
based on the 53c875, are definitely a good choice.
