[BUG?] APM is hidden in menuconfig

Hi,

I needed APM to have poweroff on old box. So, in 2.6.24.2 menuconfig:

1) Power management options -->
No APM.
2) [*] Power Management support
No APM. I can see ACPI...
3) I try searching with "/" + "APM"
APM [=n]
Depends on: !X86_VOYAGER && X86_32 && PM_SLEEP && !X86_VISWS
4) I check above: all correct except:
Symbol: PM_SLEEP [=n]
No more "depends on".
5) Exit menuconfig - enter grep:
6) Some time wasting in arch/.
7) less kernel/power/Kconfig:
config PM_SLEEP
bool
depends on SUSPEND || HIBERNATION
default y
...
config SUSPEND
bool "Suspend to RAM and standby"
depends on PM
depends on SUSPEND_UP_POSSIBLE || SUSPEND_SMP_POSSIBLE
default y
---help---
Allow the system to enter sleep states in which main memory is
powered and thus its contents are preserved, such as the
suspend-to-RAM state (i.e. the ACPI S3 state).

8) Back to menuconfig:
[*] Suspend to RAM and standby

Bingo! APM revealed! (And not even "DEPRECATED"!)

So, has it to be so hard? It seems not - at least in good old times...

Regards,
Jarek P.
