Is there a way you can disable or customize the notification bubbles on Lucid?
Yes you can, using a tool called Notify OSD Configuration.

You need to restart your computer after either one of these changes for them to take effect.

This can be seen in the 12.04 system file (NB 10.04 predates this):
[D-BUS Service] Name=org.freedesktop.Notifications Exec=/bin/sh -c 'if [ ! -x /usr/lib/notification-daemon/notification-daemon ] || [ "$GDMSESSION" = guest-restricted ] || [ "$GDMSESSION" = gnome-classic-guest-restricted ] [ "$GDMSESSION" = default -a "$(basename `readlink /etc/alternatives/x-session-manager`)" = gnome-session ] || [ "$GDMSESSION" = ubuntu ] || [ "$GDMSESSION" = ubuntu-2d ]; then exec /usr/lib/notify-osd/notify-osd; else exec /usr/lib/notification-daemon/notification-daemon; fi'
What follows is explicitly for the 12.04 redirected question.
