How exactly do they not work then?

Try it, but I think if that was the problem your modes would get rejected. Do
you use Option "UseFBDev"?

Yes. If the internal video isn't the default framebuffer device (where the
initial console comes up on), you'll have to add

	Option	"fbdev" "/dev/fb1"

in its Device Section though.

Actually, the bus ID is needed there because the higher level PCI code of the
X server will deactivate the chip otherwise. :)

(it can't determine the connection between the PCI and framebuffer devices
automatically)

There's an fbset option to select the framebuffer device, the second monitor
is probably /dev/fb1 .
