The Nvidia requires a huge great binary driver which means you won't get
any support from anyone but Nvidia (because only they have all the code).
The earlier ATI is well supported (R200 etc), the R300 is despite ATI,
and latest ATI is not supported at all (even 2D) properly because ATI are
actively blocking it.
They also have an interesting habit of dropping support for chipsets without telling anyone. The 97xx dropped support of the 440go chipset and there was no mention of it in the readme or on the website. (Which is what I have in my laptop.)

Keith Packard being one of them.
Not speaking for my employer here but personally, right now I'd recommend
the Intel setup for a quiet life and for just about anything but heavy
gaming. The 3945 wireless requires a little bit of fiddling as its not
entirely free software yet but that is all being fixed right now.
The hard part here is the desire for 64bit. Intel seems to have made it as difficult as possible to determine if a processor is 64-bit or not.
At some point I need to replace my 3 year old laptop to something that will last another three years. It looks like it is going to be as difficult now as it was when I bought the last one.
Another issue with the Intel chipset is that you cannot just go out and buy an Intel video card. It has to be on the motherboard or an OEMed card that came in the machine. (Onboard video usually gets disabled by anyone who wants performance because they use "shared" memory in most cases. Even worse is when they pad out dedicated ram with shared memory, which can cause striping effects on output.)
So far there are no real good options for video. If you get the video card with open source drivers, you are limited in what processor you can use and what motherboard you can buy. For some hardware configurations, you have no open source options if you want fast graphics or hardware acceleration.
It bites but it bytes.
