Installing a recent distro is not desirable as they resemble me only of a Open Source Vista distro, where it takes months to clean up the unwanted garbage and bloat inside. Its preposterous that a upgrade to a recent kernel mandates the installation of a recent distro. I run Mandrake 10.1 with kernel 2.6.15 and some applications upgraded like firefox, mplayer and k3b etc. Robert -- Robert M.
