Except your patch removes this hunk:

@@ -2264,14 +2248,6 @@ static int __init apm_init(void)
apm_info.disabled = 1;
return -ENODEV;
}
- if (PM_IS_ACTIVE()) {
- printk(KERN_NOTICE "apm: overridden by ACPI.\n");
- apm_info.disabled = 1;
- return -ENODEV;
- }
-#ifdef CONFIG_PM_LEGACY
- pm_active = 1;
-#endif

in apm.c and a similar piece of the ACPI initialisation that prevented
one initialising if the other had already initialised.
