That is because DVI connector does not have DDC:

(II) RADEONHD(0): Connector[0] {RHD_CONNECTOR_PANEL, "LVDS LCD1", RHD_DDC_1,
RHD_HPD_NONE, { RHD_OUTPUT_UNIPHYE, RHD_OUTPUT_NONE } }
(II) RADEONHD(0): Connector[1] {RHD_CONNECTOR_VGA, "VGA CRT1", RHD_DDC_0,
RHD_HPD_NONE, { RHD_OUTPUT_DACA, RHD_OUTPUT_NONE } }
(II) RADEONHD(0): Connector[2] {RHD_CONNECTOR_DVI_SINGLE, "HDMI_TYPE_A DFP1",
RHD_DDC_NONE, RHD_HPD_0, { RHD_OUTPUT_UNIPHYA, RHD_OUTPUT_NONE } }

It's weird that PANEL does have DDC while it uses AtomBIOS probably. Maybe that
RHD_DDC_1 should be assigned to DVI, not PANEL?
