Yeah -- discussions on this mailing list have concluded that this
phenomenon is related to the size of the kernel (or subtle differences in
the location in memory of some parts of it), but it is not a simple
relationship: kernels built from different configuration files (but same
sources) may differ in respect to allow automatic rebooting on cx and
SE/30 machines, but rebooting kernels may be smaller than some and larger
than some other non-rebooting kernels.

I've never seen any specific evidence about what causes this problem, and
after I got my Quadra 610 working, I retired my IIcx -- which solved this
problem for me :-)
