Yep they do have mobile version of the Fire and the Quadro's, as well as the Gforces (not too sure about ATI but I would assume so) ive got a Gforce 7900 GTX 512Mb Go card in my laptop (the go signifies that is's the mobile version.

With maya a dedicated card rarther than an intergrated card will help out, for hardwarerendering and possibly for display properties (as ive said i've seen problems on intergrated graphics)
