(This isnt even an X issue, as I have the problem even with just a
console display ...i.e right after booting, before entering startx.)

Just to be sure that it wasnt a hardware problem, I tried out the Fn+F7
cycling on Window$. As on my old TP600, it has 3 states, LCD, CRT or
both LCD+CRT.

Does anyone know a solution to this? How about the T21s that came
pre-installed with Caldera? I need both displays during presentations.

I know of no problem with this with the Caldera-based preload models. In 
fact, we used a T21 with Caldera preload to drive Sam Palmisano's 
LinuxWorld keynote presentation, with the external monitor going to the 
main LinuxWorld projectors and the LCD allowing us to control the 
presentation from behind the scenes. Which X server version are you using? 
Also, does Tim Robert's "s3switch" utility properly enable simultaneously 
display of monitor and LCD?
