As this wasn't getting much attention, and because I needed KVM, I decided to install Debian Squeeze amd64 on this box instead. KVM now works perfectly.
Unfortunately, this now means that I cannot test any more the problem that I had with Ubuntu 12.04. So, unless anyone else is affected by this bug, I guess it will get closed.
