I don't know if this has anything to do with anything, but on the Dell Latitudes
we have (C600's? I think)--they have ATI Rage 128 Mobility cards--you can use
the 'Option "Display" "Mirror"' to do something like that. Of course, that doesn't
mean it'll work for you--as a matter of fact, I think there's actually different
syntax for a similar option in the documentation on the XFree86 site (which didn't
work for me).
Anyway, hope you get it fixed.
