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.
