Resume on a Thinkpad L512

Hi,
My first test was with debug.acpi.resume_beep=1 in /etc/sysctl.conf and
/boot/loader.conf. I didn't know which is the right file to set this, so I
set it in both.
No debug beep. According to this:
https://wiki.freebsd.org/SuspendResumethis means that the wake up code
in the kernel doesn't even begin.
Anyway, I tested also with a stripped down kernel, made no difference. It
had no usb, no network...I commented out everything I could.
I tried another thing, which I have no idea if it makes any sense at all,
or if it was correct/relevant what I was trying, but I generated an
DSDT.aml file on Ubuntu, and copied to my FreeBSD system, and added this in
/boot/loader.conf on FreeBSD:
acpi_dsdt_load="YES"
acpi_dsdt_name="/boot/DSDT.aml"
Nothing changed.
Still when I resume it happens the same: I hear the dvd-rom making a sound,
then the fan goes crazy, no screen, no other lights, completely frozen, I
have to turn-it off with a long press on the power button.
Best,
Stefan
