So.. you mentioned that you are using the serial console and that
there were some changes in the hypervisor to deal with the serial console.

I sent to xen-devel some of the patches that you guys had (with
proper authorship) - especially the one dealing with PCI serial cards.
Jan found that one of them had an simple mistake of trying to use
the ports before they were initialized and fixed that in xen-unstable.
Perhaps that is missing?
