I checked the possibility of installing in Jaunty - the new driver packages require xserver-xorg-core >= 2:1.6.2, but Jaunty only goes as far as 2:1.6.0. So that's out for now.
I'm curious as to why and when the Karmic upgrades made it possible for my system to work without EXANoComposite, which clearly happened some time before Alpha4, when I did the fresh install (without xorg.conf).

Anyway, it works for me now.
