I'm afraid this is not the correct list for this question. Please try the debian-user list instead.

As you can reliably boot into single user mode, it should be possible to trace the point where the problem occurs, for example by disabling specific init scripts you suspect (rename them from Sxx* to Kxx*), by adding extra 'echo' statements in the scripts so you can see which get executed, or by adding 'set -x' statements in them to see exactly where they fail.

Did you check your /etc/inittab?

The suggestions above are not from a start-up-sequence expert, and you won't really find one on this list. If you need any more help, please ask on the debian-user list which is the right forum to help you trace this and possibly narrow this down to a specific package.
