support is planned for if I ever get hold of one of these cards ...
If the kernel team could get a card someone would do a driver.

Yep they are functionally the same

Cumana SCSI2	- FAS216
PowerTec SCSI2	- FAS216
Connect32	- AM53C94
Acorn SCSI1	- WD3393
Oak SCSI1	- NCR5380

The arm32 source tree has generic SCSI drivers for the FAS216, AM53C94, WD3393
and NCR5380. There are then front ends for each different card that manages the
mapping and any special control.

Note: the AM53C94 is pretty much functionally the same as the FAS216 however
there are a few extra features which as being experimented with so the chip
currently has a separate generic driver that may merge with the FAS216 driver
in the future.

What this means is that for a card that uses one of these supported chip sets
getting at least a polling driver up and running is fairly trivialm given the
hardware and the podule memory map.
