I was hit by that bug too on my debian and ubuntu test machines. Well, at least I think this is the same problem. Short answer: xen 4.1.1 compiled by gcc 4.6 (debian testing/unstable and ubuntu oneiric use that version) produce a broken hvmloader.
Long answer [1] Packages with fix (for ubuntu) [2] Maybe someone can use this to fix the packages in debian?
