Yes, the first two commits to the new driver [1][2] sort of cover it as "it doesn't support all the functionality of the vendor driver" and mention that IDs should be moved over. I'm not sure if the dual loading is because missing patches to drop ID overlaps, still missing functionality (AP or ad-hoc at a guess) or just a general oversight.

I'd suspected it might be the case but only worked it out actually was last week. I thought I'd ask here first in case there was known reasons for the driver overlap that I'd missed.
