This indicates that the /boot/grub/menu.lst file cannot be parsed.
Maybe it does not exist, or contains the wrong things. On wheezy it
would be provided by the package grub-legacy.

Nope, you don't even need an /etc/xen directory; the reference to
/etc/xen/travelkazoo.conf above is the config file of your VPS on
BitFolk's server.

A guest virtual machine running under Xen does not require xend,
that's purely for the host (dom0) machine. In fact since Debian
lenny you require no Xen-specific software whatsoever.
For Debian wheezy the correct kernel package is linux-image-686-pae
which will pull in the specific kernel linux-image-3.2.0-4-686-pae.
> xen utils installed is version 4.1, as is xen-hypervisor-4.1-i386 (arch is i386). update-grub2 works fine, /boot/grub2/grub.cfg exists and looks plausible, I’ve moved /etc/grub.d/10_linux to 50_linux so 20_linux_xen is first in line once I run update-grub2. I’ve been searching like mad and can’t seem to find anything else to try.
You should not be sing grub2, so this is probably the problem. You
need a /boot/grub/menu.lst which is provided by grub-legacy.
grub-legacy was probably removed during upgrade. If you install
grub-legacy it will probably want to remove grub2, which is fine.
It sounds like booting into rescue VM, chroot into install and
install grub-legacy will most likely fix things.

Worst case would be to install Debian wheezy from scratch. Notes for
that are here:
https://tools.bitfolk.com/wiki/Self-install
but I don't think it will come to that.

None of the above are required. You can remove them all and install
linux-image-686-pae.
