Besides raminit, some important fixes are still missing in the
current CVS.
src/mainboard/via/epia/Config.lb:
* chooses COMPATIBILITY mode rather than native mode
* more appropriate romcc options
src/southbridge/via/vt8231/vt8231.c:
* proper interpretation of enable_native_ide
src/mainboard/via/epia/auto.c:
* really call early mtrr
Attached patch also includes random minor fixes.
