Did you check the data book? I can't find it or I would have checked.
I seem to recall 0x92 is used for this and that, not just the game port.

Yep, it's here: http://www.national.com/ds.cgi/CS/CS5530A.pdf
This is for flashrom, which only needs to make the ROM readable and writable. No need for random other stuff (game port, etc).

Yeah, I think port 0x92 can reboot/reset the system or something alike. The code was not _using_ port 0x92, though, but rather _enabling_ it to be used by the OS (or whomever). All of this is not needed in flashrom, of course.
