    DRM/Radeon: On DVI-I use Load Detection when EDID is bogus. · fc87f13b
    Egbert Eich authored
    The Radeon driver uses the analog/digital flag to determine if the
    DAC or the TMDS encoder should be enabled on a DVI-I connector.
    If the EDID is bogus this flag is no longer reliable. This fix
    adds a fallback to DAC load detection to determine if anything
    is connected to the DAC. If not and a (bogus) EDID is found it
    assumes a digital display is connected.
    This works around problems with some crappy IPMI devices using
    Radeon ES1000.
