Sorry, I try to better explain what i meant:
In my earlier mail, what I was asking is:
since the patch to OVMF to prevent it from marking the region from 
0xC0000-0xFFFFF as read-only before invoking Legacy16Boot method is 
already present on the git I've linked, I was asking if such a patch 
should works without any further modification xen-side.
On the other hand, if you think the patch will never work without xen 
modifications, I'll not test csm now but I'll wait xen change.
