XF86Config
options The driver probes wether the chip is configured for CRT only or LCD/simultaneous mode of operation. In the former case it will enable clock programming and will support any mode which is within the limits of the hardware. If the chip is configured for LCD/simultaneous operation mode the driver will respect the settings of the BIOS and allow only one video mode conforming with the panel size.
The driver does not support interlaced or double scan modes.
