Leo Weppelman has done some work on a new savecore that supports
multiple segments, including the possibility for machine-specific
segment types.  The Sun3 needs a special segment into which the
kernel will dump a copy of the current MMU state.  The kernel dump
routine can use a small reserved piece of memory as a temporary
holding place for the MMU data that normally lives in special SRAM
inside the MMU, copying one block at a time of MMU data to disk.
The same temporary block could be used to write out a header
before everything else.

Then, savecore needs to identify the new format dump data in swap
and copy it to a file in the new, generic kernel coredump format.

This should all be reasonably easy, but I've been busy chasing
some other things.  If you'd like Leo's stuff let me know.
