How do I run an app in Full Screen mode on OS X Lion on my second monitor?

I recently bought a MiniDisplay Port to VGA to make use of my unused monitor. So far I'm using it but one thing I notice is that when I try to use the fullscreen option of a certain application, Safari for example, OS X Lion only seem to use the main display (my MBP's monitor).

When I drag Safari's window on the extended display and then fullscreen from there, the fullscreen window still returns back to the main display.

Is there a way for putting the fullscreen window to the extend display?

This is possible in Mountain Lion by dragging the window to the secondary screen before entering fullscreen, but unfortunately cannot be done in Mac OS X Lion.
