In Kernel 2.4.18-pa20 I've added a /proc/sys/kernel/power
procfs entry which lets you enable/disable the soft power switch 
at runtime:

# echo 0 > /proc/sys/kernel/power		# disables the power switch
# echo 1 > /proc/sys/kernel/power		# enables the power switch

# cat /proc/sys/kernel/power 
Software power switch support: enabled (1)

Or, you could of course also use sysctl program/interface.
