OK, so Xen uses both the serial and VGA console, and NetBSD thinks
it's a serial console.

So both thinks it's a serial console. Do you pass "console=pc" to the Xen
kernel, or the NetBSD kernel ?
For a VGA console (VGA only, no output on serial console at all) you need:
console=vga
passed to xen.gz, and
console=pc
or
console=tty0
passed to the NetBSD kernel.

I did this several times and it worked; but you have to use the
exact gmake line from the pkgsrc makefile, with the right PAE and debug
settings:
gmake XEN_TARGET_X86_PAE=n debug=y xen
(because the debug kernel is built last, and is what's left in the
$WRKSRC tree).
