I cannot replicate Stuart's successful report.  I'm sure my simulator is a 
much older build than his and Hollis' guess about device trees is another 
reason I should bring my simulator up to date.  I apologize for raising a 
problem without doing that first.  I might not get to it right away, but I 
will do it.  Hollis, why don't you not waste your time with simulator 
until I test with a current one.

RE: [XenPPC] Changeset with 3 files on Friday (I think) has brokenXen on 
Mambo







I just did a clean build of top of tree Xen and Linux and
am able to boot my dom0 kernel on Xen with the simulator.
So I'm not seeing the same issue Mark had.

Mark-- I would try the very latest just to make sure.  I
built with linux changeset ab3b5849331d and Xen changeset
ed5ee9dde0bd.

It is taking a heck of a long time though.  The simulator
cycle count appears to have about doubled.
