linux friendly laptops

[Duncan Lithgow]

Having looked around on the net I couldn't really find much about
whether any manufacturers of laptops are more linux friendly than
others. I have to buy a new one, good specs, so I'm trying to do the
right thing and support good manufacturers. The only useful things I've
heard are that ATI have opensource drivers - good, and I can see that HP
have started selling laptops with linux on. Is that a few extra points
for HP?

Anything to make my laptop hunting mission easier would be appreciated.
At the moment I can't really narrow the field enough to start checking
specs of individual components.

Oh, and I'm not in the US, I'm in Denmark, so I want a major brand not a
US only one <http://www.linuxcertified.com/linux_laptops.html>.
