What I am suggesting is that we should accept the memory
sizes which correspond to what can be represented in dc0
(which presumably correspond to possible real hardware
configurations) and not any memory sizes which can't be
represented by a dc0 value.

I don't know what you mean here, because ram_size is given
to the board code as a value in bytes. The M and K prefix
stuff is just user convenience when they specify values on
the command line.
