I found a dumber solution (than editing the apt sources):

(1) run "sudo update-manager -d"
(2) choose the distribution upgrade option
(3) let Ubuntu download the update tool
(4) run the update tool until the first packages
are downloaded
(5) without aborting the upgrade* (yet), run synaptic as a regular user
(6) click on the icon "Mark All Upgrades"
(7) choose menu "File / Generate package download script"
(8) abort the upgrade

You are now ready to run as a regular user the that consists of a series
of "wget package.deb" lines.

The downloaded packages can then be copied over
to /var/cache/apt/archives using either (a) synaptic
or (b) a simple "cp" command.

[*] No changes will be made to the system until
all packages are downloaded so it should be safe
to run and abort the update until then. Unless
you're downloading just a few MB's or KB's of
files, you should have at least a few minutes to
abort before the upgrade reaches the point of
no return.
