ACPI S3 mode wouldn't work correctly every 2nd time, also stock hibernate action leads to a crash every time

[Voron_Shinigami]

While I was using Ubuntu 9.x with its stock kernels, suspend and hibernate functions worked properly, except that the keyboard power on feature didn't. Once I upgraded to 10.04, the system began not to turn power off (as expected) after S3 mode initiated every 2nd time, when it was S3 standby (suspend) function, I had to turn the system off using the power button, resulting a crash session end. Once tried to use stock power management hibernate function, the result was powering off without actually saving the session image to swap, leading to the same crash result. Then I tried to use the hibernate package script, and it worked with --force option, because the nvidia driver kernel mode prevented hibernation another way, but, the same I had to use power off with the power button pressed and held down 4 sec every 2nd time to shut down. After all that, I also tried installing never mainline kernel versions, first it was 3.0.0.x (backport-oneiric) from kernel PPA, then 3.4.x.x-precise, from DEB packages downloaded together with the headers. I had also to uninstall the repository current proprietary nvidia driver and install one from the *.run package downloaded from NVIDIA site, to make the graphics system work on 10.04 with 3.4 kernel. 3.4.x.x-quantal kernel didn't work with nvidia driver at all, cos' it wouldn't compile the module, generally because of the difference in gcc versions.
With 3.x kernels, the keyboard wake up from ACPI S3 began to work again, but the problem with not turning off each second time persists. My system is based upon NVIDIA NFORCE 4 Ultra chipset (ASUS A8N-E Socket 939 mainboard), AMD Athlon X2 3800+ CPU, 2x512Mb or 4x512Mb Transcend DDR400 (PC3200) memory modules in dual channel, 128-bit mode (other memory configurations and video card / other peripherals were also used time to time, nothing changed).
I'm using AMD64 versions of Ubuntu.

version no more supported; not a 'security' problem, so no backport expected
