I myself was looking for a laptop (see my recent posting "My Big Fat Question-laptops and animation" and I'm probably giving up for now and getting a full-sized system (see my even more recent post-"What do you think of this System?).
From my research it seems if you want a serious laptop the only graphics card is the nvidia quadro4 (or 2) Go GL, found only in the Dell M50 and the Fujitsu Celsius H-the "dream" laptop that animators in the US want but is available only in Europe (I fear the price!)
I'm currently corresponding with Larry Donofrio of Fujitsu - Ldonofrio@fujitsupc.com - He's supposed to get back to me any day now with info. When I know it I can post it-or you can ask him yourself.
Hope this helps!
