For those that have the same problem, I had to do the following...
Enable the DOC2000 hardware driver and NFTL, and it should turn up as /dev/nftla. Needed to create some nftla devices, i.e.
brw-rw-rw- 1 root root 93, 0 Sep 15 12:01 nftla
brw-rw-rw- 1 root root 93, 1 Sep 15 12:01 nftla1
brw-rw-rw- 1 root root 93, 2 Sep 15 12:01 nftla2
brw-rw-rw- 1 root root 93, 3 Sep 15 12:01 nftla3
