I'll have a swing at this on Thursday (though I ought also to be looking
at ARM MMU/barrier things and the AMD/XP/TPR issue).  I have win2003
install media and am familiar with the RT code now. 

But for the record, I have no objection at all to reverting the whole
lot until the release is out -- clearly we don't have the test coverage
to be sure that this hasn't caused problems for any other guest OSes. 

Tim.
