No EGPWS Alert on a coupled ILS Approach

Jagohu said (in post 356 )
"I don't really know about this A/T disconnect theory - if you go below the GS you'll get the GPWS alert straight away, so I guess you'll notice it, don't you? Not talking about the altitude alerts of the GPWS."
.
The theory in post 348 was that the a/c stalled whilst on a coupled ILS and because the "non auto-throttled" autopilot was maintaining the ILS glideslope at the expense of speed (i.e. kinetic to potential energy) - and not dropping below it and triggering the EGPWS alert.
