Um. Let me try again.
Soft power-down isn't a standard part of a PC. Linux doesn't know how to
do it without APM or ACPI.
APM is out the question on SMP, due to the way it's designed.
So you need ACPI properly working for soft power-down.
You've added acpi=ht to the kernel boot flags.
This is defined as "ht -- run only enough ACPI to enable Hyper
Threading" (in /usr/src/linux/Documentation/kernel-parameters.txt). In
other words -- not enough to do soft power-down.
