Both times 0x09? Or is this a typo?

Are you sure this is the correct patch? It doesn't seem to match the
datasheet in a number of places, e.g. 0x20 and 0x21 (IDs) are incorrect
in NOLDN (as well as most other values in NOLDN), some registers are missing
completely, some LDNs are missing completely etc.

Is this for another Super I/O, or remainders of copying another table?
