Im not sure it is possible to use your laptop as a controller. However, If you just want to use a USB Keyboard and USB Mouse. What I use is a XIM3 (www.xim3.com). They cost about $150 US, and are very close to PC control and feel (its noticable on some games rather than all). But I would say about 90% good translation. I use it with my xbox 360 along with a Steelseries 6v6g and Logitech G9x. In addition there is an email posted on the forums from Microsoft Support reguarding legality (<-if that's a word). It is allowed on Microsoft's Live service.
