Can 4850's run in software crossfire w/o interconnect

I just installed my second 4850 and my interconnect cables will not be here until Wednesday. Should I be able to run both cards in software mode or not? I'm not so much concerned from a performance aspect since I will be getting the cable in two days, but I want to know if I have a problem that I should look into correcting before the interconnect cable arrives. I'd rather spend Wednesday enjoying the computer rather than working on it.

Agreed, I just want to know if I "should" be able to enable crossfire right now without the interconnect. It's not necessarily that I think I would get much benefit, just to rule out any potential issues before Wednesday.
