The output printed after NormSpeed was and is correct, as was all the
outer text output, but under the hood it did always set 16.5MHz instead
of what the user requested.

You would need to checkout my github repository. The two patches you
need are inside the flashrom_next branch:

No idea. If it is not included with the default build of coreboot it is
probably not mandatory. I remember that there was some work done
regarding writing an open source firmware for it. You better ask
coreboot at coreboot.org or on IRC.
