PROMs *do* have interesting ideas sometimes.

Sure you aren't. If you have a 64-bit machine, it's relatively easy in
fact. If your code and data is above 512 MB, you are a little more
screwed, but it still can be done (as evidenced by me), and CPHYSADDR does
not, enter the discussion at all. All you have to do is create a correct
memory map at start.

I don't know about running mapped kernels in 32-bit mode, though. It is a
different thing whatsoever.
