SLI/CF with multi monitors.. Can You use four monitors while not gaming

I have no doubt this could be accomplished by turning on and off SLI/Crossfire in the BIOS for whatever task is at hand, but That would be insanely annoying to me.

I have a Quad monitor setup, ASUS M2N32-SLI Deluxe, currently with an 8800GTX driving the two larger displays, one of which I game on, and a 8600GT driving two smaller displays that I drag various windows and control panels onto while working. (Pretty much all 2D/Video work on these monitors)

It would be awesome if I could have say two 4850s or two 9800GTXs in CF or SLI mode that would switch automatically between being able to use all 4 monitor ports while not gaming, and auto switching to SLI/CF mode when gaming.

Do modern drivers do this? Or do you have to reboot every time?
 
ATI cards in CrossFireX don't need to disable it (and then reboot) when going from multi-gpu gaming mode to multi-monitor normal.
 
I use 3 monitors on my SLI rig atm, the Nvidia drivers have improved to the point where I can enable/disable SLI via the NV Control Panel about 90% of the time without being forced to reboot.

I was also using the 3rd card trick to get the the 2 additional monitors working with SLI enabled, but it's been somewhat unstable with the last few driver revisions so I've stopped doing it.
