I had the same problem. The problem was "udev" refused to install because the kernel didn't match. And then everything else break, mostly xorg because he needed a new udev. Or something like that.
I solved the problem that i just installed the new squeeze linux kernel (2.6.32), reboot and then restart aptitude. With a normal "aptitude install linux-image-2.6.32-5-amd64" or whatever kernel you use, it should only install the kernel. After new linux image installation and reboot, upgrading to squeeze works just fine without an error. -- To UNSUBSCRIBE, email to debian-laptop-requ...@lists.debian.org with a subject of "unsubscribe".
