Solved finally.
Ricard's comment about s2ram helped greatly, thanks!
pm-tools now do not apply any video "quirks" for nvidia cards, but it looks
like one is needed
for this notebook:
--quirk-s3-mode (equivalent to s2ram --apci_sleep=2)
To make default suspend working following is needed:
1) Copy - sudo cp /usr/lib/pm-utils/sleep.d/98smart-kernel-video
/etc/pm/sleep.d/
2) apply following patch (also attached):

FYI - if you want to use s2ram instead of the kernel suspend just try this (but
previous fix is still needed!):
1) Install - sudo apt-get install uswsusp
2) Edit /etc/pm/config.d/00sleep_module
put SLEEP_MODULE="uswsusp"
