In short: The udev from sid breaks ugrade process because it doesn't support kernels < 2.6.12. There is no kernel 2.6.12 packages in the distro, yet. As far as the more packages depends on newer udev (i.e. alsa-base, usbmount) I have to hold on more and more packages. See Bug#317332. It seems to me as BTS-wars :( -- .''`.
