What happened here is the following.
1) i only analysed the first part properly and missed GPIO16 getting 
raised. It is this part of the code, and only this part that is needed 
to get all the board fully supported.
2) the superio poking code in the bios was absolutely bogus. Logical 
device 06 is the spi interface on this superio, while the rom is lpc.
The register writes to 0xF0, 0xF1, 0xF2 also suggest that it is setting 
a gpio line, which is usually logical device 7. Bogus code.

We got away with just raising the ich9r gpio16 :)
