Thanks, but I'm not sure that at a "high level" this is a good idea.
I don't think SeaBIOS should be altering coreboot information.  (Doing
so leads to all sorts of painful debugging problems, for example.)  If
memtest86 is having problems with the coreboot tables I suspect it
would be best to alter memtest86 to not read the coreboot tables.
