Any way to have my 4850 and my 3450 installed, but only one powered at any time?

I've got a P5Q PRO, unpossible?

Quite happy to swap the display connection at start-up, depending on whether I'm going to game or not, but it would be a total pita having to physically swap cards each time.

With my 3450 I was using about 60-70W for office/net/email/HDTV/DVDs, with the 4850 I'm doing the same things at 110-120W

Q6600/4GB RAM/750GB 32MB Spinpoint/PCI HDTV tuner/2x120mm/1x80mm are the other loads in the case.

Bump, in the hope that some post-Christmas cheer will get more response

ATI has mentioned the possibility of enabling something like this in their drivers, but so far they haven't.
Currently only nvidia supports such a set up, and not even on all sli mobos.
