This enables access to the EDID transferred from the firmware.
On the i386, this is from the Video BIOS. Enable this if DDC/I2C
transfers do not work for your driver and if you are using
nvidiafb, i810fb or savagefb.
In general, choosing Y for this option is safe. If you
experience extremely long delays while booting before you get
something on your display, try setting this to N. Matrox cards in
combination with certain motherboards and monitors are known to
suffer from this problem.
