To date there is no way to run a more than one external monitor from a MBP in the conventional sense. At least the last time I checked there was no PC card video adapter. However there is a box out there that splits the video from the DVI into 2 DVI's and allows a single video connection (up to the rez of a 30" monitor) to span 2 smaller monitors. Of the many downsides to this approach is that the menu bar will be split in two.
This is one of my few complaints with the MBP. My teammates Dells can run two monitors (one from DVI and one from VGA) however I notice that they never use the screen of the laptop itself when the machine is thus docked.
