It might be that the IOMMU has an errata and Xen refuses to enable it.
Can you provide the serial output when you try to boot Xen + FreeBSD?
You might have to add console="com1,vga" to your xen_cmdline (although
AFAIK that's the default).

The command line looks fine IMHO.

Yes, both series need to be applied. If you find issues applying them
ping me and I can rebase them if needed.
