Yes, you only applied the patches that allow the FreeBSD loader to load 
Xen, but you also need all the patches for the FreeBSD kernel that 
enable PVH mode and Dom0 support.

The list is quite long TBH, and I haven't looked at whether all of them 
are needed or not, but a good start should be:

I don't think all those are needed, you will have to look at each one 
and apply the ones that are related to PVH or Dom0 support, giving a 
proper list of the exact patches needed is not a trivial task at all.
