Thanks a lot for all these changes. I've attached the new version
modified with you advice.

Now, I did download the release-notes from SVN, as per the link Julien
provided. But I failed to understand what file I should modify in it
(I've searched...). This information is missing at
http://www.debian.org/releases/squeeze/amd64/release-notes/ch-about.en.html
(it only tells about SVN).

Please help me to get this addition in.

Cheers,

4.7.4. Xen upgrades

In Lenny, if you installed Xen, the kernel that grub-legacy would boot by default was the one providing a Xen hypervisor and dom0 support. This does not happen under GRUB 2 in Squeeze. Instead, the non-Xen kernel will boot by default. If you need Xen and expect to boot with it by default, you have to tweak the GRUB 2 configuration as explained at:

http://wiki.debian.org/Xen#Installationandconfiguration

Also, upgrading from the Lenny version of Xen does not automatically install the current 4.0 version. So, after you finish the dist-upgrade, you should use an explicit "aptitude install" for Xen 4.0 and a corresponding dom0 kernel. See the wiki page for instructions on how to set up the Xen hypervisor and dom0 kernel under Squeeze.

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 because of a request from the mainline kernel maintainers. Instead you should use (as a corresponding example) xvda1, which always work, including when running Lenny 2.6.26 forward ported Xen patch.
