On the QEMU side xen_add_to_physmap is the relevant function. However I cannot see how it would be different from qemu-xen-traditional.
Well my description was not completely accurate, when the memory address is retrieved for the first time (vga.c:2225), qemu can write to it, but after some point (don't know exactly yet), the userspace process looses access to that memory region, and gets a segfault.
