Could it be that you don't load button module?

I'm trying to upgrade a cluster from Mandrake 10.1 (with 2.6.8.1
vanilla kernel) to Mandriva 2007 (2.6.17-8mdv kernel). These machines
have Tyan S2466N-4M motherboards, single AMD Athlon MP 2200+ processors,
and the latest (and no doubt last) BIOS = 4.06. ACPI is enabled in
the BIOS.
One test node was upgraded and worked correctly except for one
annoying problem: afterwards that node would
no longer respond to the front power button following a
"poweroff". To reboot that system it is now necessary to pull
the power cord, count to 20, plug it back in again, and then push
the power button.
There were a variety of changes to the acpi between those kernels
versions, but the one that I think maybe indicates the problem
is the new
/proc/acpi/wakeup
file, which on the problem machine contains only:
Device Sleep state Status
PCIO 5 disabled
OP2P 5 disabled
USB0 1 disabled
So I tried: echo "OP2P" > /proc/acpi/wakeup
which strangely enabled both of the first two
entries, neither of which was "* enabled", just "enabled". This
was not enough to make the power button work following
a "poweroff".
Those 3 wakeup devices were all that was listed in /var/log/dmesg,
so it isn't that the OS dropped the power button after the BIOS
reported its presence, it seems that the BIOS never told the OS
that the power button exists. (How this worked with the older
OS I have no idea). Sleep states listed in /var/log/dmesg are:
ACPI: (supports S0 S1 S4 S5)
Here are all the ACPI lines in /var/log/dmesg:

On other systems (different motherboards and processors) with
recent kernels this /proc/acpi/wakeup contains either
PWRB 3 * enabled (Mandriva 2006)
or
SLPB 4 * enabled (Mandriva 2007)
and those machines do boot from a power button push following
"poweroff".
Boot parameters for both the working and nonworking Mandriva 2007
machines were the same (other than different partition numbers):
image=/boot/vmlinuz
label="linux"
root=/dev/hda5
initrd=/boot/initrd.img
append="resume=/dev/hda2"
The ACPI entries in config are:
CONFIG_ACPI=y
CONFIG_ACPI_SLEEP=y
CONFIG_ACPI_SLEEP_PROC_FS=y
CONFIG_ACPI_AC=m
CONFIG_ACPI_BATTERY=m
CONFIG_ACPI_BUTTON=m
CONFIG_ACPI_VIDEO=m
CONFIG_ACPI_HOTKEY=m
CONFIG_ACPI_FAN=m
CONFIG_ACPI_PROCESSOR=m
CONFIG_ACPI_HOTPLUG_CPU=y
CONFIG_ACPI_THERMAL=m
CONFIG_ACPI_ASUS=m
CONFIG_ACPI_IBM=m

CONFIG_ACPI_BLACKLIST_YEAR=0
CONFIG_ACPI_EC=y
CONFIG_ACPI_POWER=y
CONFIG_ACPI_SYSTEM=y
CONFIG_ACPI_CONTAINER=m
What steps do I have to take to get a power button
device into /proc/acpi/wakeup???
Any idea why the older kernel's ACPI variant was happy start up
from the front panel power switch following "poweroff", but the
newer one isn't? (There were no specific acpi kernel switches).
