I have an HP zv5000z laptop. It has an AMD64 3700+ running FC3.
Using the supplied kernel cardbus does not work.
Using this patch (attached) cardbus works fine.
What does it take to get this added to the Fedora kernels so I don't
have to rebuild every kernel upgrade?
Do I need to send Penguin Mint bribes to Alan Cox?
