Hi Roberto
The 2.4.22 kernel does have ACPI built-in, and the modules are
definitely there:
$ ls /lib/modules/2.4.22-1-686/kernel/drivers/acpi/
ac.o battery.o fan.o thermal.o
asus_acpi.o button.o processor.o toshiba_acpi.o
I just doesn´t seem to be starting during kernel boot-up with the Debian
kernel. Although, as I mentioned, it does work correctly with a standard
ftp.kernel.org kernel.
Regards
Damien
