The ram is 32-bit, the question about overlap with PCMCIA is about address space, but checking e.g. sysinfo, it's easy to see at which address the memory is mapped.

What did you mean, when you say "not updating"? SPRxPOS is write-only, and only really useful when not using sprite dma (unless you're doing fancy tricks mostly used by demos/games).

But does using MEMF_24BIT even make sense on an A3000/A4000 with motherboard or accelerator board ram? It would use chip ram for the rom remap, which isn't even cacheable?

No ID stream from DF0 is only true in case of a 3.5" DD drive - maybe that's why the kickstart pulses select a few times to check if anything (special) is there..
