[gumstix-linux] Enable DVI display output on DuoVero

Even though the Parlor board does not have a DVI out, Geppetto boards
may.

As a side note, the DSS and its drivers should be built into the kernel.
Building them as modules requires loading (modprobe) omapfb kernel
module to get a display output.

unresponsive system.
