PowerPC has both segmentation and paging. Segmentation
and base-bounds is ugly dead-tech from last century which
has been proven redundant when a grown-up paging mechanism
is provided. May segmentation rest in (odd-sized,
hard-to-manage, barely demand-swappable) pieces. :)

If someone tells me you can turn off the segmentation
logic in some variant of PowerPC, I might change my mind
about it. :)

Agreed. 6502 expanded to 32 bits would be very nice.
Some changes would be needed to make it gogofast, like
a good cache system and possibly a more load/store
orientation and more registers. Which is pretty much
what ARM is.

Have you looked at the ARM instruction set? It actually has
a lot of similarity to a "stretch" 6502. :)
