Exactly, and this is an area I am interested in pursuing.  Hence, the
interest in Dave's machine.  I haven't gone through enough pSeries
architecture documentation yet to know what to expect.  One would think
that a smaller lmb size would be better for hot swap memory.  At least
in the 'remove' side of the equation.

Yup.  I think I'll try to put together a 'hack' to make the memory
layout on my 615 look like one of the bigger machines with dynamic
LPAR capabilities.  In other words, multiple (smaller) possibly
non-contiguous lmb's.
