[PATCH] x86_64: Search K8 devices on more devices.
arch/x86_64/kernel/aperture.c: The search for the AGP bridge has been extended to search for all the 256 buses instead of the first 32. This is required since on a some systems, the bridge may be located on a bus much farther than the first 32. By searching all 256 buses, we guarantee that the search succeeds on such systems. arch/x86_64/kernel/pci-gart.c: The search for the Northbridge is not limited to just bus 0 anymore. This is required because on certain systems, we may not find one on bus 0.
