You can use GPIO from AMD8111 and SuperIO Winbond 86327hf. But you need to check which pin can be linked out.

We've got Linux up and running on our Tyan S2885 motherboards, using etherboot and filo with USB support. Thanks for all your help, and patience!
I was hoping that with all the expertise here with AMD 8111 chipset, that someone would be able to answer my question. Although it's not strictly LinuxBIOS, it is Linux. ;-)
So I'm trying to write a Linux driver for the GPIO pins on the AMD 8111. I saw a comment in amd8111_smbus.c that PMIOEN is set. I believe this is part of what I need to be able to drive the GPIOs.
But how/where were all those hex values determined? The spec uses mnemonics to abstract the addresses, and I don't see how they correlate.
Thanks,
