"toshiba" is only available with Realtek ALC861 codec.

There is no "2stack" anywhere, at least not in 2.6.23.

These model names are codec-specific -- you can't use them with every
Realtek codec, though some codecs do share common model names like "3stack".

Is it really using that name, or rejecting it and falling back to "auto"?
