Looking for a Linux friendly laptop

I finally decided I needed a laptop. My dream machine would meet the following criteria:

• Linux friendly. I would like to "vote with my wallet" and buy a machine for which there exist open source drivers for all components.
• I will be compiling a lot with it, so it should be quite fast at this. This means a fast processor, a decent hard disk and not turning into a bakeoven everytime a binary is linking.
• Not the size of an aircraft-carrier. But not too small too.

If you know the model of my dream machine, please tell me!
