Ubuntu developed a tool called 'jockey' for installing hardware drivers. There is an ITP for it in Bug #436722. Jockey is in my opinion the best place to do something like this. I CCed Martin Pitt, the developer of jockey (and quoted the remaining parts of the email in case he did not read the original one). > > Each package would provide a list of patterns for the hardware it > supports.
