I didn't know they'd started splitting this into chip-_sets_. :-)

AFAIK this is the Symbios Logic LSI 53C875 (also known as NCR 53C875) HBA.
Not only is there driver code (for e.g. Linux I believe) to draw experience
from, Symbios (now LSI Logic: http://www.lsilogic.com) have at least
previously been very good at providing easy accessible specifications, and
even sample code. IIRC they used to have a rather extensive FTP site while
they were symlogic.com. Perhaps lsilogic is as good?

Just for kicks, I did check and... Well, for anyone interested, I believe
the following document from their LSI8751SPE page is about what's needed
(watch the wrapping):

rs/875_4_2.pdf

If every vendor was as good documenting its hardware as these guys, life
would almost be good.
