Issue #455 has been updated by Angel Pons.
Have you tried running `sudo superiotool -d`? This should show the register dump for the Nuvoton Super I/O on your board. The AST2400 detection procedure is delusional (read random registers, if any returns non-zero then we have an AST2400), so it often results in false positives.

Without debug symbols I can't use gdb to provide more useful information.
