If you would like to see a package backported, file a bug report. Before you do so, however, make sure it meets the guidelines for backporting set by the Ubuntu Tech Board:

* Must be present in the development version of Ubuntu. Use http://packages.ubuntu.com/ to search for the package, make sure it is present in Feisty Fawn. Again, a package cannot be backported unless it's already in Feisty.

* Must remain backwards-compatible with existing components. This means that major revisions of libraries cannot be backported, as well as other packages that will introduce incompatibilities with existing Edgy components.
