My question is: I cannot choose a page size depending on the
particular MIPS CPU model because once the package is built it could
be run on a CPU with a different page size, is that right?

If that's the case then I should use a conservative value that is
guaranteed to work on all models (64KB, or is 16KB safe?).

Ok, I'll use 64KB then.
