* Merge from Debian Unstable. Remainning Ubuntu changes: + debian/control: - Add quilt to build-depends for Ubuntu patches + debian/patches/100_radeon-6.9.0-bgnr-enable.patch: - Smooth plymouth transition enablement patch + debian/rules: - Add xsfbs patchsys - Drop /etc/modprobe.d/radeon-kms.conf install. + debian/xserver-xorg-video-ati.{pre,post}inst.in: - Clean existing /etc/modprobe.d/radeon-kms.conf on install. At best this does nothing (KMS is the default for our kernel) and at worst it makes it harder to disable KMS. * Add debian/gbp.conf pointing to Ubuntu branch to make git-buildpackage less narky. * Drop 102-no-xv-rn50.patch and 103_new_pci_ids.patch from previous Ubuntu releases, they are upstream now.
