Since I can easily reproduce this I will investigate further to see
what's going on.

Once Dom0 is started Xen will not output anything else to VGA, so you
won't be able to see any Xen messages unless you use xl dmesg.

Probably, but without a serial console it's impossible to tell. Can you
apply the following patch to FreeBSD and rebuild the kernel?

Sure, no problem.
