A couple of weeks ago, I got a new Laptop for work: a Dell D830 with Santa Rosa Chipset. A nice machine, but it couldn’t run Kubuntu with Beryl and all the nice graphics features I use to make Vista look pale.
To solve the issue I backported a couple of packages from gutsy to feisty (all amd64) and stored the debs in a repository. You can read all about it here. The page features a description on how to build the packages. It also has the link to connect to the repository.
