    drm/kms: start adding command line interface using fb. · d50ba256

    [note this requires an fb patch posted to linux-fbdev-devel already]
    
    This uses the normal video= command line option to control the kms
    output setup at boot time. It is used to override the autodetection
    done by kms.
    
    video= normally takes a framebuffer as the first parameter, in kms
    it will take a connector name, DVI-I-1, or LVDS-1 etc. If no output
    connector is specified the mode string will apply to all connectors.
    
    The mode specification used will match down the probed modes, and if
    no mode is found it will add a CVT mode that matches.
    
    video=1024x768 - all connectors match a 1024x768 mode or add a CVT on
    video=VGA-1:1024x768, VGA-1 connector gets mode only.
    
    The same strings as used in current fb modedb.c are used, except I've
    added three more letters, e, D, d, e = enable, D = enable Digital,
    d = disable, which allow a connector to be forced into a certain state.
