OK, I might have gotten some interesting data. First, I should explain. I decided gain (after a couple years) to switch to fglrx and see how it works. Last time it was also very buggy but in more annoying way... So I installed fglrx and it... didn't giving me configure errors with my custom kernels , I did not want to bother any further. So I decided to switch the sides again :) and removed it. I tried to see how suspend-resume would work (DRI and 3D was on). So it did not, however, instead of usual blank unresponsive to SysRq keys monitor I had a dump and REISUB restarted the machine. Oops I did it again, and got nothing gain... :) In the usual way all resume attempts were numb, no syslog info was left. The corresponding kernel.log (the section between the sleep and a waking attempt) is attached below. I hope that this would be helpful for more knowledgeable people than me. --
