Hi,
for your question :
This is a summary of what I have done:
I set the APM option in the kernel 2.2.10.
if I do "halt", my box act like the use of "reboot" : it reboots
using the shutdown of windows95 act as i want : power off the computer
the command :
#ps aux |grep apm
root 2169 0.0 0.3 1148 416 pts/0 S 15:39 0:00 grep apm*
to be sure I am recompiling my kernel.
