I fixed up all issues I could see and committed a merged version from
your patch and the one from NTU (kept both Signed-off-by's) in r6131.

If you have a board with the 0909 ID you can test on, feel free to post
a patch which adds at least detection support for that chip. Until we
have a datasheet to check the registers I'd rather not add any guessed
register values to superiotool, though.

NTU, can you please post a "superiotool -d" output (use the latest
superiotool from trunk) from your board?

Thanks, Uwe.
