Updated Feisty today and after restarting (new kernel) and logging in, I was prompted with a balloon indicating that Ubuntu may be using restricted drivers. Clicking on the new tray icon in the notification area popped up the following window:

I like how it informs users in rather polite language that proprietary drivers are almost impossible for anyone but the driver’s vendor to support.

Perhaps it could contain a link to a list of equivalent hardware that is fully supported by open source drivers? Free marketing exposure for hardware vendors whose products offer open source drivers could help encourage more vendors to see the light.
