Yes, that's the correct solution here.  I originally thought this
couldn't be done, but in looking at the code some more, I think it can
happen for the network driver, and perhaps some others (but not the
block, as both devices work off of the same interface to the hypervisor,
so which one do we load?)

I'll look into that later if I get the chance.
