bootdev is right, although I don't have this problem with any of my
DomU's, only Dom0,
grub.conf:

default=0
timeout=2
fallback=2

title NetBSD/Xen
 root (hd0,1,a)
 kernel (hd0,1,a)/xen dom0_mem=128M dom0_max=128M
 module (hd0,1,a)/netbsd bootdev=wd0a console=tty0

title NetBSD/Xen (prev)
 root (hd0,1,a)
 kernel (hd0,1,a)/xen dom0_mem=128M
 module (hd0,1,a)/netbsd.xen_old bootdev=wd0a console=tty0

title NetBSD/AMD64
 root (hd0,1,a)
 kernel (hd0,1,a)/netbsd.generic

I've an addition if you're wanting to add more:

if [ -r /kern/xen/xenbus ]; then
        if [ -f /usr/pkg/etc/rc.d/xend ]; then
                /usr/pkg/etc/rc.d/xend start
        fi
        if [ -f /usr/pkg/etc/rc.d/xenbackendd ]; then
                /usr/pkg/etc/rc.d/xenbackendd start
        fi
        if [ -f /usr/pkg/etc/rc.d/xend ]; then
                /usr/pkg/etc/rc.d/xendomains start
        fi
fi

in your /etc/rc.local saves polluting /etc/rc.d and nicer when boot a
non-xen netbsd kernel
