If you have grub-0.97nb5 installed from pkgsrc, then I think you can 
fake out the grub-install script by manually creating a device.map file. 
  The lame BIOS drive detection in grub doesn't work correctly for ld(4) 
devices, but if you manually create a /grub/device.map file containing 
the line:

	(hd0)	/dev/rld0d

Then re-run that grub-install command you have above and see if that 
installs GRUB properly on your system.  This is what I did on my own 
machine.

No, there is no way to load the Xen hypervisor using the NetBSD boot 
loader.  The boot process works by asking GRUB to load the Xen kernel 
with the domain-0 kernel as a module.
