I can't imagine that there would be much demand for such a beast, so I
would be quite surprised to see one available as a commodity item.

Depending upon what you want to do with the "other" external monitor,
you may be able to use a USB-video adaptor (essentially an external
frame-buffer connected via USB). You won't get 3D or full-frame video
performance, but it should work fine with X and do all the usual
standard stuff ("my mail window and other bits and pieces...").
Whether there is a Full HD version available, I am not sure.

Otherwise, X is a network-extensible windowing protocol, so you could
have another laptop (or desktop) hooked up to your "other" external
monitor and use X (or VNC etc.) to display your windows to it. Again,
performance is not going to allow you to play first-person shooter
games etc. to it.
