Unfortunately with iommu=0 Xen doesn't boot at all for me. I see this
on the console:

(XEN) Panic on CPU 0:
(XEN) FATAL PAGE FAULT
(XEN) [error_code=0011]
(XEN) Faulting linear address: 00000000328b3a54

Not sure what's up with that. Either way, can you post a git branch
with the remaining patches that are not yet merged in master? Want to
check if those patches resolve the issue.

Thanks,
Tamas
