Ah, good point. If you have a "major" change, e.g. the kernel jumps from
2.6.16 to 2.6.18 or some such, then you also need to do (on target
system):
# depmod
# mkinitrd /boot/initrd-2.6.18-xen 2.6.18-xen 
(Adjust version as applicable of course)

For very minor upgrades, it's often enough to copy just the xen.gz to
/boot on the target system - but that's if you know exactly what's
changed!
