+The driver probes the chip to find out if a flat panel (LCD) is connected
+and active. If this is true it limits the possible screen size to the maximum
+resolution of the panel. The chips is initialized by the BIOS which may
+set the chip to 'dual' mode even if no panel is connected. In this case
+the available resolution on the CRT is limited to the panel size
+the BIOS has set. To tell the driver that no panel is connected despite
+of what the BIOS is saying set this option to off. Don't set it to off
+if a panel is connected.
+Default: value probed by BIOS.
