I can do this, but it may depend on the notebook you use. I have a Fujitsu S2210 running Vista with an ATI Xpress1150 integrated controller. I have to follow the following sequence to make this work:
1. Using the function key combination to swap monitors, (Fn F10 on mine), I set it so that only the external monitor is enabled.
2. Then, (as this is now the primary monitor) I use the windows display manager (in Vista you can access this through Windows key & 'X') to select the notebook monitor as my extended desktop.

thanks a lot for the trick with the function key, I pressed FN and then hit one after another all the f1, f2, F3 etc until one started to affect my dual monitors, (F5 or 6) And,lo + behold, my laptop screen (HP) was suddenly switched to secondary, the ext, monitor has become primary. All I had to do then was to play with activate-desactivate to wake it up from its black screen state. Now I will be able to send the primary screens image to my big screen TV or my video-recorder simply by replacing the external monitors VGA cable with the S-video cable. This is nice because all ppt-files (Powerpoint diaporamas) obstinately only show up on the primary monitor, and as long as the external monitor is not primary it was impossible to send any ppt presentation to my recorder+TV setup.
