Thanks. Indeed, there was some possible confusion. Patched accordingly.

Please find the new patch attached to this email.

+If you installed Xen on Lenny, the kernel booted by grub-legacy per

+Upgrades from Lenny will not automatically install Xen version 4.0. Instead

+Be aware that, if you run a pvops kernel for your domU, like the Xen kernel
+2.6.32 of Squeeze, your domU won't be able to use (for example) sda1 as a
+device name for its hard drive. This naming scheme has been removed from Xen
+upon request of the mainline kernel maintainers. Instead you should use (as
+a corresponding example) xvda1, which will always work, including when running
+Lenny 2.6.26 forward ported Xen patch.
