Using two displays with a MacBook Pro

I would like to set up a 24" monitor and 30" monitor with my 15" MacBook Pro (v4.1).

The graphics card is the GeForce 8600M GT 512MB.

It's important that one of them be color calibrated using my Eye One Display 2.

Is there an external peripheral that can make this work?

If it's not possible because my computer is too old - does buying one of the more recent MacBook Pro's make this possible?

Thanks
