3dmark06 has been designed for current top end kit, you will only get smooth framerates from a high end machine.
3-4 fps is normal for this machine, remember that the overall score doesnt reflect the x1400 against an older card, because the 1400 supports more 3d features and tests. so you should look at the individual scores for the various components I.e. CPU score and GPU score.
I got 900 or so points on my test
one piece of advice that really does speed up one of these laptops is to get rid of Nortons crippleware and get hold of AVG or similar.
Nortons while being thorough on the systems security side of things uses, far more resources than other solutions, and hence slower performance.
