Can't configure NULL in metamode
Status: Beta

The specification of NULL in the metamode is useful
when you are defining a device that is not always
attached (like a TV). For example:
Option "MetaModes" "800x600, 800x600; NULL,1600x1200"
The keyword "NULL" is not recognized by yanc, and it
generates an invalid syntax.
