Almost everything working nicely. Problems that remain:
-Headphone output has slight interference noises (in Windows too, though - it's purely a hardware issue)
-Sleep mode doesn't work (but software suspend - hibernate - does, with the proper config, and loss of hardware graphics acceleration)
-not-so-great battery life (~2.5 hours)

I got the Intel 2200BG wireless and the ATI Radeon Mobility X300 video. The former in particular is highly recommended, and works almost out-of-the box.
