Have you tried booting (with the device plugged in) into single user
mode, then trying to convince the system to use the built in screen as
the default device (fn-f7 on my machine), and finally exiting the
single user shell to go multiuser?  (One could also hit fn-f7 while
the system has the grub screen displayed and then go straight to
multiuser.)

I need to use such tricks since my laptop is 1680x1050 while the
external monitor is 1600x1200.  I find that having the (text) output
already directed to the external monitor (mine defaults to internal)
prior to xdm/gdm invocation is useful (necessary?) to get 1600x1200
resolution.
