After some twiddling it all works rather well, I’m amazed how well ;) Even suspend to ram works flawlessly! (that was a different case a year ago, when I last had linux on a laptop). The only things I still have to get working is the framebuffer console (so I get something better than 80×25), and the infrared. Nothing very high on the agenda, though :)
I’ve detailed the installation instructions in this post.
