That processor is supposed to have the PRUs, so I'm not sure what's going wrong. I don't have a BBGW to test with, but I think some other folks have worked with this board and didn't run into any unusual problems.
Let us know how things go with Jessie. Using Jessie + a 4.x kernel should be pretty straight-forward.
