Looks good, but it's been some time since I tested Xen with a VGA console.

Can you try to change load /netbsd.dom0 console=com0 while keeping
console=vga for xen.gz ?
This will let xen use the VGA console, and the NetBSD kenrel will
just use the Xen console (via hypercalls) instead of trying to
drive the VGA console itself. This won't probably give a working
keyboard, but hopefully some more details will be displayed ...
