DMI-based keymap solution requires kernel upgrade every time new model is out whereas configurable keymap can be loaded easily form userspace. Also user might want to remap keys to do different stuff. For example I never change brigtness on my laptop now that I found settings that I like. So I could map one key to start kmail and another one to build kernel for example ;) -- Dmitry - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@...r.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
