I am just guessing here, but if the manufacturer says 256MB is the
maximum, I would expect that the unit is not able to address more than
256MB memory, regardless of the amount you plug in to it.

Apart from the fact what is better than something else: I think it is
very brave to use unsupported hardware to operate a network. If
something fails, you are on your own then. No support from the vendor.
One of the things where being brave and being insane are only seperated
by a very thin line ;-)
