Verify that the /etc/ttys change is made.

Try "console=com1,vga" and "com1=115200,8n1,pci" in the Xen string in 
loader.conf

Using an ExpressCard serial interface, I had to set the setting manually:

set comconsole_pcidev=5:0:0
set comconsole_port=0x4000
set comconsole_speed=115200

That's all I have figured out so far. Do share if you get it working.
