Yeah, I figured this out a while ago. Unfortunately, I'm in the middle
of changing employers so everything's in boxes at the moment.

Basically, the swap space is hard-coded into the device drivers. If you
take a look at, for example, the RK05 driver you'll see that one of the
drives is smaller than the others. That extra space is the swap space.
I forget how the rest of the system is informed of the swap space, but
it's done in the disk driver sources IIRC.
