Well, I fear you'll have to. I've come in this issue twice
with large
partition, and did never see it with small ones. I suspect
grub is, in fact,
not 64bits safe. When you install the xen + netbsd-XENx_DOM0
kernels just 
after the netbsd install, it's likely to end up physically
near the start
of the partition. But after some time of filesystem
activity, files
copyed to / ends up past some limit (maybe 8G ?) and grub
can't load them.
It's not a matter of kernel size; just moving these files to
a smaller 
partition made grub able to load them.
I think it's mandatory to create a small / partition for Xen
installs. I'll try
to add a note about this in the FAQ.
