So I've just checked it. And... nouveau is in fact NOT changing refresh rate 
AT ALL. I mean, it is not fisically changing anything. After I execute the 
above command, xrandr says, that the refresh rate has been changed (the '*' 
mark is moved to the 60Hz frequency. But my monitor, which has an ability to 
report its current refresh rate, still reports the same (91.2kHz, 85Hz) 
rates. So it seems, that --rate parameter does exactly NOTHING in the 
nouveau case. Isn't it strange? I can change resolutions, but I cannot 
change frequency...

Still, since I was not able to check the above, no solution for my problem 
has been found. Any more ideas? Anyone? For now I'm forced to switch back to
