Mike, please try disabling LVDS in your /etc/X11/xorg.conf:
In section "Section "Device"" add the line:
Option "monitor-LVDS" "LVDS"
Then the following new section:
Section "Monitor" Identifier "LVDS" Option "Ignore" "True" EndSection
If that solves the problem, let me know and I can put in a quirk for it.
