Big thanks to the original reporter, Bj=F8rn Mork, who found what the issue is. See http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=3D572991 for the bugreport in question, together with the resolution. In short, when vgabios were dropped from qemu-kvm (for whatever yet unknown reason), all local changes to it were dropped too, including this patch: http://git.kernel.org/?p=3Dvirt/kvm/qemu-kvm.git;a=3Dcommitdiff;h=3Debf= ac597cf Note that this patch is present in upstream 0.6c version of vgabios, but not in 0.6b+ which is currently used in qemu. Should vgabios in qemu include that patch?
