The kernel does not rely on any floating-point, so that's no problem.
Does it use MTPR for console in/out? If it does, it will be simple to
get the kernel to say at least "hello". 
Is there some sort of VMB in prom? How does the machine boot?
Part 2 of this is to make the uba routines to stop careing about map
registers, but that will also be rather simple I suppose.
