this just works... at least on my t40
but it's not REAL suspend - it uses a lot of power.
all you need to do is

 echo 3 > /proc/acpi/sleep

I've given up on acpi for this reason...
I don't know whether it can be fixed or not (it may be that acpi S3 is
not supposed to be equivalent to APM suspend to memory)

you need to learn about acpid
put this into a file in /etc/acpi/events

event=button[ /]power
action=/etc/acpi/powerbtn.sh

then when you push the power button that script will get run.
