heartbeat, too, works across 32 and 64 bit just fine, even in mixed
clusters.
However, you _are_ testing something quite unlike the hardware
environment you'll actually be deploying. Out of general principles,
that's not good - because in _theory_ it should work, but if theory was
all you were interested in, you wouldn't be testing at all, right? ;-)
So yes, testing on the production system seems in order.
