Yup, sounds like that's the problem. Here's a quick patch to fix it
by adding a rom_enable() function (and converting VT8231 to
TINYBOOTBLOCK) while I'm at it. The only problem: It won't compile ;)

    ROMCC      romstage.inc
non const static variables not supported
make: *** [build/mainboard/via/epia/romstage.inc] Error 1

No time to investigate right now, if someone else sees the problem,
please feel free to fix and commit. Probably just some missing
"#if defined(ROMCC)" or the like.
