ubun2^beta

I have an Nvidia GeForce 7300LE and a GeForce FX 5200, with four monitors.  Back in the days of Feisty Fawn, I tried getting this system to work with Ubuntu, but had a problem being able to drag windows from the display of one graphics card to the display of the other card.  Is this resolved in the current release?  What will I need to do to configure it correctly?
