The WD1007 emulates at the register level the "standard" AT drive controller
(for instance, the WD1006), so no special drivers are needed for it.  I have
one in the machine I'm using now, and it has vanilla 2.3.1 running.

To use one of these as a second controller it would need to be set up at a
different interrupt and I/O address, which I don't think either of these can.
