Notifications from signing on/off in pidgin can be disabled trough pidgin (Tools / Plugins / Libnotify popups / Configure Plugin).
Reverting to the old notification system can easily be done by installing gnome-stracciatella-session, then log out and finally selecting "GNOME (without Ubuntu specific components)" session before logging in. Took me 20 seconds, and I can switch back any time I like. Look at http://martinpitt.wordpress.com/2009/02/23/the-stracciatella-gnome-session/ for more details.
However, I do agree that there should be an option - the current positioning does not work at all for me due to bugs. But as I said, it is easy to revert to the old system (took me a while to find it).
