As a workaround, one can boot with
menu=Boot Xen sync:load /netbsd-XEN3_DOM0 ; multiboot /xen-debug.gz dom0_mem=256
M console=vga sync_console=true vga=text-80x80,keep

With this xen keeps control of the VGA console and the NetBSD kernel
can print on it. You don't have keyboard input, but at last you can see
the boot messages
