dmesg reports: [ 29.365973] [TTM] AGP Bind memory failed.

[ 29.366996] [drm] radeon: ttm finalized [ 29.367030] [drm] Forcing AGP to PCI mode This patch allows binding user memory to the AGP GART on zx1-based systems. dmesg thus no more complains about AGP bind memory failure, disabled GPU acceleration or AGP mode forced to PCI.
