Maybe you shouldn't think of this as a script. Rather think of it as
hints for apt/aptitude to do a dist-upgrade in multiple steps. As you
say the maintainer scripts should do the right thing already. So it is
just a matter of splitting up the package list into smaller chunks so the
upgrade process doesn't explode with a few extra actions inbetween
steps.
For ia32-libs the extra action would be "dpkg --add-architecture
i386". For the kernel/udev the action might be "reboot". Little things
like that. :)))
In general the upgrade "script" could consist of lists of white/black
lists of package to be processed in each step and debconf messages being
displayed between steps prompting the user to do certain things before
continuing.
Each time dist-upgrade-by-script is run apt-get would skip all the steps
that produce no change and continue from the first one that does (in
case it was aborted or reboot was needed).
Just an idea. Not that I think this could be done before the freeze.
