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?
