Is it wrong ? because i can't see any options for the APM on the
kernels .config and on make menuconfig.
If I recall correctly, APM implies calling 32 bit code in the BIOS.
Therefore, it is unlikely to work in a 64 bit kernel without a lot of
effort by the kernel developers.
It's just to have the battery stats working and to shutdown properly whithout
i press the power button after the last kernel message ACPI_POWER_OFF called
I've been using ACPI calls for battery, cpufreq and shutdown. The
former works and the latter doesn't. However, I haven't taken the time
to figure out why the 32bit ACPI shutdown works and the 64bit one does
not, because I rarely actually shut down.
