    agp: add chipset flushing support to AGP interface · a13af4b4

    This bumps the AGP interface to 0.103.
    
    Certain Intel chipsets contains a global write buffer, and this can require
    flushing from the drm or X.org to make sure all data has hit RAM before
    initiating a GPU transfer, due to a lack of coherency with the integrated
    graphics device and this buffer.
    
    This just adds generic support to the AGP interfaces, a follow-on patch
    will add support to the Intel driver to use this interface.
