It should be, although I had issues while using the vesa driver with a
FreeBSD Xen Dom0, mainly because Dom0 doesn't have access to the BDA and
EBDA, I'm working on fixing this in Xen upstream.

So you are trying to use the serial console but you are not getting any
output? If that's not the case, please drop the com1 parameter and set
console=vga.

Do you have anything else in your /boot/loader.conf apart from this two
lines?

On which device do you get a login prompt? Is it xc0, ttyv0 or ttyu0?
