I have seen/heard of this type of setup using VNC before. See for example:

On your workstation you would modify your X setup to extend the virtual display, and run a VNC server to display the extended portion. On your laptop you would run a VNC client fullscreen (and probably want to turn off power-saving features).

I have no specific recommendations beyond that. For your Google-foo, the search I did to find the link above was "vnc extra monitor".
