The mailing list has reports from happy users who have been able to get Amithlon fully working on their laptops (including sound and LAN once the latest kernels and contribs are installed).
However, since laptops vary so much and the Amithlon kernel is quite customised, there's a good chance that a fair number won't work without modifucations.
I'm not sure anyone has collected an updated and accurate compatibility list following the latest contrib release.
