It's not even a hack with the ACA500. Just install an ECS Agnus (if you don't have one already), install a trapdoor expansion and select the "ChipMap" feature in the expert menu of your ACA500. That will give you 1M Chipram.

2M Chipram is a bit more complicated, because the Agnus has a different pinout, and memory must be installed in addition to what's already there on the board. If you're a solder expert, you might be able to do it within a full working day, but I consider that very risky if you don't have a verified design on a known-good expansion board (aka 2M Chipram expansion for the Agnus socket).
