dual cards on linux and a failing x server (Score 1)

Does anyone know how to get X going on dual video cards or is this is even possible? I have had absolutely no luck getting X to start with two cards in my box, I have to actually remove one before booting into linux.

Anyone pulling this off? If so how, the dual monitors thing is one of two reasons micro$oft still owns my desktop.

(the other is lack of software support for apps I enjoy using such as homesite, paint shop pro..)
