Register 0x24 says ROM size is 2 Mbit.
Register 0x2a says flash translation is enabled.

We should autodetect this Super I/O and set bit 3 in register 0x24 to
enable detection and writing.

We have a patch for this somewhere, but it is probably pretty bitrotted
and needs to be updated. Would you be willing to test a few patches?

Sure. I am not used to patch/build, but I think I will be able to get
it done. The instructions on <http://www.flashrom.org/Downloads> don't
seem too hard. It will take some time however, until I can test the
patched version on the mainboard. I expect to be able to test it on
one of the next weekends.
