I have the same problem. But I think it is an user-space problem.
Probably there should be no CONFIG_APM_POWER_OFF and we should have
a power-off option to /sbin/halt. I have solved this problem by
binary-editing /sbin/halt (i have replaced a LINUX_REBOOT_CMD_HALT value
by LINUX_REBOOT_CMD_POWER_OFF).

Maybe the power-off should be the default on i386 architecture,
because on i386 there is no PROM monitor, which the LIUNX_REBOOT_CMD_HALT
could switch system to.
