Heh, as you can see I hesitated closing this also.

IIUC dual-link DVI does not work with the Windows driver either (but I have no
confirmation). I'm a bit on thin ice here, but I don't think increasing the
HDMI frequency directly helps dual-link DVI unless there's some active
components supporting dual-link. It depends on how the DVI port is set up I
guess.

Adam, are you running at least kernel v3.11?
