Dual monitors with Advanced mini Dock and T61 - CTO or T60p

[ShadowRider]

I have two different systems: T60P with the ATI video card and a T61 with integrated graphics.
I will be receiving a 2503-10u advanced mini dock (very reasonably priced at the IBM used PC store - about %30 MSRP) today.

I have 2 20" analog LCD screens. I would like to be able to use both monitor with this setup (laptop screens closed). Will one or both of these systems be capable of this?

What do I need to drive the second monitor from the DVI-Digital port since it would seem I need to go from digital to analog?

Thanks.
