You have a VGA or DVI output ? VGA I think ? It should work with
Michel Danzer packages but it will be an analog output, not as good
as a fully digital.

XFree doesn't drive properly a DVI output on a laptop yet, though
I got it to work with a small userland hack I use to "fix" the chip
after X configured it ;)

Note that you may also have a problem with XFree not setting the proper
divider for your internal panel when used without UseFBDev. Same issue,
I have a userland "fix" for that since fixing it in XFree itself isn't
quite simple at this point.
