With Joomla! 1.6 it is possible thanks to multiple groups per user and custom view levels. Here's the deal:
1. Create a new user group
2. For each user you want to see the module, add him to the new group
3. Create a new View Level which only the new group can access and name it "Backup Notification"
4. Edit the Akeeba Backup Notification Module and set the view level to "Backup Notification"
...and done!
