Ok, I will write that up and post it here next week.

What do you mean by "VME64 addressing capabilities"? If you're talking
about accessing VME A64 space, the Tundra Universe-2 VME interface chip
on the MVME5500 doesn't support accesses to that space at all (you need
a board like the MVME6100 or MVME3100 that uses the Tempe TSI-148 chip
instead for that). If you mean the ability to use VME64x geographical
addressing, isn't that what the CR/CSR space is for?
