Here it is:
Add specific configuration for Samsung NC10 mini notebook.  Internal
mic/speakers will be correctly muted when plugging in external ones.
Mixer controls are added for speakers, headphones and PC beep.
"Boost" is added for the microphones.

Ok, did that.

I rebased using 20090509 snapshot before sending the patch (I checked
out today's snapshot too - patch_realtek.c hasn't changed), and those
models were there indeed.  However, I wanted to try those
configurations but I couldn't use the model= option because the
configurations were not in the alc662_models array.  That's why I
added these 2 lines, and it got through to the patch.  I removed them
for now, as that should probably be another patch.
