Not working at all for me unfortunately. Maybe I am flunking the
modeline math, but I think that this specific driver (openchrome) has
special hardcoded magic for our display.

That modeline is what Xorg reports when it autodetects the modeline --
using the exact same modeline via explicit declaration kills the
display. So this driver ain't a friend of modeline tweaking.

Do we have a VirtualAndIMeanIt stanza?
