I tried, none of them worked.

uswsusp didnt't work either. After reading Suse ACPI page
(http://en.opensuse.org/S2ram) and debuging the suspend process
(http://en.opensuse.org/ACPI_Suspend_debugging) i realised the problem
can be related with BIOS or a kernel bug.
Here what they say:
If none of the methods described here seem to work, it is important to
check if the machine is completely dead on resume or only the video is
not resumed properly. A good way to check this is to start with a
minimal system (init=/bin/bash), run s2ram -f, and after resume, when
the display is still off, check if the "Caps Lock" key still works
(you should see a reaction of the Caps Lock LED on the keyboard). If
it does, it is most likely really a video initialization problem. If
it doesn't, then it is most likely a BIOS problem or a bug in the
Linux kernel.
After adding the init=/bin/bash to kernel parameters and suspending
with echo mem > /sys/power/state, it woke up with a blank screen but i
wrote "find /" and see the hard disk led blinking. I pressed ctrcl+c
and entered the echo mem > /sys/power/state command again, after
pressing the power button, i see the blank screen and tried the find
command again. This time i didnt see any hard disk led running. So
seems my problem is not related with the POSTing video. It is posting
video a the first try, though. in the X environment.
Is there a method to reset the memory areas that are being used during
suspend process. After the first suspend and waking up from it
succesfully i may reset "things" and maybe this time it will work.
