kaf24@scramble.cl.cam.ac.uk 2dfd28a23f bitkeeper revision 1.1159.187.28 (41aa30ddzQc4QQ8kotJ3RHoG7dhzsQ) 
Update the AGP+DRM patches for 2.6.9, and automatically patch the kernels
before we build them. Also avoid using virt_to_phys() in our virtual drivers
as we may change what it does -- better to use __pa().
