Hi,

Since the recent ACPI import (i believe), it seems that ACPI is no longer
disabled when APM is enabled. I do not explicitely disable API anywhere,
I have the following configuration:

device.hints:
hint.apm.0.at="nexus"
hint.apm.0.flags="0x20"

kernel config file:
device          apm
device          pmtimer

In the past, I have seen upon bootup a message "apm: Other PM system
enabled." and the kernel would carry on booting as if ACPI had not been
loaded. Now I see the following:

FreeBSD 5.0-CURRENT #15: Thu Aug 29 16:54:05 BST 2002
    root@epsilon.ury.york.ac.uk:/usr/obj/usr/src/sys/EPSILON
Preloaded elf module "/boot/kernel/acpi.ko" at 0xc05742fc.
...
apm: Other PM system enabled.
acpi0: <TOSHIB 750     > on motherboard
acpi0: power button is handled as a fixed feature programming model.
Timecounter "ACPI-safe"  frequency 3579545 Hz
acpi_timer0: <24-bit timer at 3.579545MHz> port 0xfe08-0xfe0b on acpi0
acpi_cpu0: <CPU> on acpi0
acpi_tz0: <thermal zone> on acpi0
pcib1: <ACPI Host-PCI bridge> port 0xcf8-0xcff on acpi0
...
acpi_lid0: <Control Method Lid Switch> on acpi0
acpi_cmbat0: <Control method Battery> on acpi0
acpi_acad0: <AC adapter> on acpi0
atkbdc0: <Keyboard controller (i8042)> port 0x64,0x60 irq 1 on acpi0

etc.

Although apm -z still seems to work as expected, closing the lid causes
havoc with my IDE controller (i guess it's no real suprise given APM and
ACPI are fighting over what to do).

I can do a binary search of commits if required, but am pretty certain
this is new within the last three days.

Gavin
