- GenX MATH: NOPs needed for divide ops. With optimized caching and pipelining, the CPU's instructions are faster, b/c they don't need to schedule the bus.
- FA2560K TEXT: legacy mode works so long as you don't exceed 8k each of text/attributes; new mode not fully tested, but basics are working!
- 68040/68060: Even with caching disabled, you should still configure the I/O address region(s) for "serialized" access. Otherwise, the memory controller might re-order reads and writes on you!
