Full Screen Magnifier - possible to change zoom resolution?

[aw]

When I use the full screen magnifier (via FN-Space), the screen resizes to 800x600 as it should.

This is pretty cool, but, does anyone know if it is possible to change the zoomed in resolution?

Ideally, what I'd like to be able to do is have it switch to 1024x768 when zoomed in. Can this be done?

If you press FN-Space there is a little icon showing up in the tray. By clicking on it you can choose your resolution.
160% is 1024x768 in my case.

Thanks - I hadn't noticed that icon in my tray before.
