Some more responses after my first summary of my original question:

From: Kevin Sheehan {Consulting Poster Child}

It's actually a break that does it...

..and there is actually a way. Break is sensed by the zs (serial)

driver and

calls prom_enter, prom_enter_mon, or debug_enter or somesuch depending

on release. You can patch the driver to NOP out that call. Depends on

your adb skills and ability to find the call in zsa_?int routines.

Terminal server or serial connection from another machine is usually the

answer. I think there was even a "Consulting Special" that just didn't

sense break, don't know if it still even exists, and would recommend

doing

it another way anyway.

Umm, did no one mention that the 'kbd' program (and accompaning

'/etc/default/kbd' file) can manage this under Sol 2.6. Now, you

won't be able to halt the machine if you need to, but it won't go down

if the terminal is power cycled.
