If an address is in the range [MININT..MININT+{2 or 4k}), the transputers
simply don't generate an external bus access. Thus, the T225's internal 4k are
mapped into that region, and the external memory's first 4k will be mapped
onto [MININT+32k..MININT+36k), if indeed the highest address bit is ignored by
your hardware. Where's the problem?

As for getting the stuff you want into internal memory, look at the
configurer's and linker's maps, and read up on the #pragma statements to move
selected parts about.
