Yes, you can install what's missing: There is some possibility that these packages, too, have missing dependencies that need to be installed. In a few hours or days, I'm sure you'd get it.
You could, alternatively install 12.10 and download and install linux-image-3.5.0-25 where your device is supported by default.

I took your advice and installed 12.10 and linux-image-3.5.0-25 , now I have no wireless mouse. Any ideas what I could have done wrong and how to correct the problem?
