If my understanding is correct, you want to have an option value that has a mainboard specific default value, but that can be overridden in the target configuration file?
If this is the case, then my preference would be to do something like the following in the mainboard file:
if ~ ROM_IMAGE_SIZE option ROM_IMAGE_SIZE = 65536 end
where the '~' operator means "hasn't been set".
It seems to me this would be clearer than changing a default value, possibly after the value has already been set.
well, guys, here is how it works not.
ROM_IMAGE_SIZE is define in Options.lb (read first) with no default value.
In the config (e.g. targets/via/epia/Config.lb) you can set something like: option ROM_IMAGE_SIZE=512*1024
If there is no setting, then what applies is in the mainboard file:
default ROM_IMAGE_SIZE=256*1024
however, I did not know about this 'hasn't been set' stuff. Sorry. Greg, I have no problem with that.

The problem is you're relying on obscure behavior of an option. You're setting (or not setting) an option in the target config file, then subsequently changing it's default value, then using whichever happens to override the other. See my reply to Mark.
