    I don't like this much - while it solves a setup where you use both
    kernels, it isn't solving a 2.4->2.5 transition for not-really-skilled
    users. I think Linus's way is the best here - provide both /dev/sda, ...
    and provide also major/minor aliases (which will go away later) as
    /dev/hd*
