I may be able to (briefly) get my hands on one, and if it uses an
fas216 I would imagine I could get the same functionality as the
cumana/powertec/connect32 as they all use the same chip.

Yup, but the information I have seems to be missing some

Well the easiest way (used by most ports), is to have a chip specific
section of code and a card specific section that accesses this.
See: ptsc.c sfas.c and csc.c
