Did it ever work for you?

Thanks for the dumps. I believe the Super I/O data sheet is incomplete
and/or wrong, so please try this patch against superiotool and dump
again under LB and proprietary.
Look for undocumented SIO6 registers in the IT8716F Super I/O. This is
just a shot in the dark, if it does not yield the expected results, we
have to dump and compare the whole chip. If that is not sufficient, we
have to dump GPIO space (well, we should already do that, but we got by
without it for a long time).
