For installing Debian on a laptop, I find this list:

The laptop I'm installing Linux on is almost always there, with a lot of details, real XF86config, etc. Is there something like that for the Macintoshes? A page listing the pages of people who succeeded on installing Linux on such or such Mac and giving details?
