I'm, perhaps, 1 micron closer to the objective.  The 30 pin SIMM diagram (link follows immediately) tells the tale.

It comes down to whether or not the chipset can drive the A11 line, at the appropriate times.  A11 is connected only on 16 MB "slugs".

Ah, hardware "joys".  As irritating as this stuff is to me, I think back to the IBM 360F30 I started on in Feb. 1972.  That machine's microcode ROM required compressed air, in order to function correctly.  I'm NOT joking.  Look card read only storage (CROS) up.
