I would recommend anybody to contact Canon technical support to show your interest in Linux drivers. This is the only way Canon will hear the Linux community.

I just want to remember that Dell preinstall Ubuntu on some of their PC since IdeaStorm: Popular Ideas - Dell IdeaStorm

You can show your interest for Linux drivers for instance here:

Canon Europe - Registration

or in any Canon support site. Even if you receive the answer that they do not support Linux drivers, you let them know that Linux exists.
