Strange. None of the changes in my patch show up in your superiotool
output. That either means these registers are special or some part of
the patch was ineffective or it was not applied.

The changes in superiotool output have no relation at all to the patch.
LDN 0x7 idx 0xc9 should have value 0x40, but your diff claims it is
still 0x0. Since everything else is normal, the only possible conclusion
is that you either booted an image without my patch (not necessarily
your fault) or something magic resets all values to those from a
revision without my patch.

Did you remove the build directory before rebuilding? Did you power off
the machine before booting with the patch? Can you run superiotool
before running flashrom?
