Or Radeon HD 3650?

I am curious how these ATI mobile GPU chips/drivers work with Linux.

I am looking at laptops and the choices are those v.s. ones with Nvidia 9300 GS (I think GS)?

For e.g., Lenovo Thinkpad T400 w/ Radeon HD 3470
v.s.
Sony Vaio Z590 w Nvidia 9300GS

Any other choices? I am looking for top screen quality, LED backlight and preferably DDR3 RAM but not essential.

I think I named the top two and I post in the ATI section since I am more concerned about notebooks with ATI GPU because of the uncertain and controversial graphics drivers situation.

Please comment and recommend?

I want the option to watch movies/video on the notebooks so I would like a decent screen (w/ LED backlight).

I prefer the Intel wifi 5100 or 5300 (looking for the 5300) as well.

I suppose the ATI 3470 cards will work but how much trouble is it configuring in Linux? I'll use Ubuntu or Debian. Thanks.
