The Page Frame Table moved out of ESQA/ECSA in OS/390 2.10, so that shouldn't 
be an issue.  I don't think there would be any change in HSA either.

I'd been thinking about this. Wouldn't the ESQA increase in size to
track the increased number of page frames (needed by RSM)? This would
push ECSA a bit higher (address floor is what I refer to here, not
size). 

HSA will get moved. And it might increase in size (I don't know how IBM
handles tracking of storage for LPARs -- I knew how this worked on
Amdahl 5990-A machines once upon a time).

But other than those things, I can't think of any thing else that gets
changed.
