If you have multiple modes in the display section in your xorg.conf you 
should be able step through them using control-alt-plus and minus the 
viewport will be a small fraction of the 1920x1200 display (you'll be able 
to fly around using the mouse) but it works.

When I have to do presentations (I have an inspiron 6000 with 1920x1200 
display) I typically run a another xserver on display :1 with a 
viewport/resolution that natively matches that of the projector (either 
800x600 or 1024x768) that way I edit my presentations on display :0 and 
switch over to :1 when it's time to plug into the projector and present.
