I'm afraid my digging didn't prove to be very enlightening. One thing I'd
like to try, is to see if we can reproduce the problem on an 11MPCore
platform with a CPU > r0p0. However, I don't have access to such a platform
that can run mainline, so without that I think we have to go with Russell's
workaround predicated on a check for 11MPCore.
