The patch was not included, and it won't be since it has too many problems.

As mentioned in the other thread, the chip appears to be built specifically for ASUS,
and neither ITE nor ASUS are willing provide datasheets which would enable us to add
support for the chip into Linux.

ASUS is an interesting company. On the one side, they claim to support Linux
on their web site, but when contacting technical support they state that
they don't, and that they won't even provide chip datasheets. From what I heard,
that used to be different. No idea why they changed their policy.

Not that we would ask for active support, but passive support (ie providing chip documentation)
would be nice. Until that happens, if it ever does, I can only recommend not to use ASUS boards
if you want to run Linux, if you need SuperIO chip support, and if the SuperIO chip is not
already supported by Linux.

Thanks,
Guenter
