Hi again Sean Hammond:

Concerning the "signal out of range" a thought:

1. Copy /etc/X11/xorg.conf from a working install.
2. Compair with what you have when "signal out of range" occurs (less
and vi very useful here).
3. Look specifically at the horizontal and vertical sync rates - if
the "signal out of range" xorg.conf is different make it the same and
try the results.
4. Check out the other differences.

Good Hunting!

Tod
