drm/radeon: upgrade to 1.27 - make PCI GART more flexible
radeon: make PCI GART aperture size variable, but making table size variable This is precursor to getting a TTM backend for this stuff, and also allows the PCI table to be allocated at fb 0 radeon: add support for reverse engineered xpress200m The IGPGART setup code was traced using mmio-trace on fglrx by myself and Phillip Ezolt <phillipezolt@gmail.com> on dri-devel. This code doesn't let the 3D driver work properly as the card has no vertex shader support. Thanks to Matthew Garrett + Ubuntu for providing me some hardware to do this work on.
