Ah there's the rub - I didn't know how to force initrd creation for a
specific version from a certain directory
(/root/xen-3.0.2-2-install/lib... etc.) when I didn't realise the
install proceduce copied all the modules to /lib/modules/2.6.16-xen :)

After that I just needed to run

$ depmod -F /boot/System.map-2.6.16-xen 2.6.16-xen
$ mkinitrd -o /boot/xen.img 2.6.16-xen

And away we went - hurrah! =)

So, one question answered, and another two to replace it. :)

Xen complained about the tls stuff at boot up and invited me to mv it
out of the way, which I was expecting. Will I need to undo this if I
ever want to use a non-Xen system in future?

And finally, if I'm running Xen on amd64 hardware, can I also run amd64
VMs inside it? Is there any performance benefit/penalty for doing so?

Cheers,
Gavin.
