Merge branch 'agp-patches' of git://git.kernel.org/pub/scm/linux/kernel/git/airlied/agp-2.6 

* 'agp-patches' of git://git.kernel.org/pub/scm/linux/kernel/git/airlied/agp-2.6:
  agp: fix SIS 5591/5592 wrong PCI id
  intel/agp: rewrite GTT on resume
  agp: use dev_printk when possible
  amd64-agp: run fallback when no bridges found, not when driver registration fails
  intel_agp: official name for GM45 chipset
