Yes, I think I know what's up. It needs several hacks in XFree to
be made to work, not very simple. Nothing I can do right now, but
I can have a look later when I finally get a TFT screen myself (I
had one on loan for a while but had to give it back)
Basically, XFree doesn't quite understand that the DVI output on
those machines is actually routed to the primary TMDS and not the
secondary one. In addition, there are some fixes to do to X so
it properly disables tiling mode on the second CRTC (you can try
hacking this one yourself: clear crtc2_offset_cntl), and to
properly do detection of both heads in such a configuration.
Ben.
