I setup two different boot blocks in grub, and passed in two different cmdlines; one for 'Laptop' and one for 'Desktop'.
These cmdlines were parsed by a small startup script I wrote to copy over the laptop or desktop x configuration file. On boot, I simply select laptop or desktop mode in grub boot screen. -C > I'm working on a startup script that will copy the correct X > config into > place, depending on whether I'm docked or not.
