The only difference between ppcemb and ppc is that ppcemb supports 1k guest 
page size granularity. So all of your issues should be independent of the 
ppc/ppcemb difference.

That said, I'd be more than happy to receive patches that fix ppc405ep support 
if you encounter anything broken. It's currently a reasonably orphaned target.
