I built APM and ACPI into my kernel, when booting, ACPI says that it is
taking over APM features.
Then when I run the battery meter (this is on a laptop), it can't get the
battery state information. If I get rid of ACPI, everything works ok.
So, what is the diff between ACPI and APM and how does it effect me?
Thanks for the info and help,

1. APM vs. ACPI status detection
Hi,
I have a little patch witch sets apm_info.disabled flag not only if APM
disabled by user but if it disabled by SMP or ACPI. Please apply.

}
if ((smp_num_cpus > 1) && !power_off) {
printk(KERN_NOTICE "apm: disabled - APM is not SMP safe.\n");
+ apm_info.disabled = 1;
return -ENODEV;
}
if (PM_IS_ACTIVE()) {
printk(KERN_NOTICE "apm: overridden by ACPI.\n");
+ apm_info.disabled = 1;
return -ENODEV;
}
pm_active = 1;
