I don't know about the Natural Keyboard problem, though this
google query might help you:

As for /dev/mixer: you don't want to symlink it to
alsamixer. Alsamixer is a program, whereas all the files in
/dev/ are (basically) files corresponding to physical
devices, or abstractions sitting on top of physical devices.
/dev/mixer is supposed to correspond to an actual component
in your sound card. The way one normally creates a file in
/dev is by loading the appropriate module.

I forget which module creates /dev/mixer, but I'd bet it's
one of the snd* modules. Below is my list of snd* modules;
yours will be different, depending on your hardware, but
looking at your own list of modules (via 'lsmod') will help
you narrow it down.

If others have more specific information about which module
generates /dev/mixer, feel free to post.
