OK. That's what I have after the upgrade:

$ dpkg -l |grep firmware
ii  firmware-linux-free  3
ii  firmware-linux-nonfree  0.33

How I can find about KMS status?

Hmm. To me whole the problem is strange - I think there should be no 3D
or it should be at some little variable FPS change after the upgrade,
but it works as follows : from about 420 in Squeeze down to 60 Wheezy...

Therefore I want to find out the culprit - it worked and worked much
better than now but something drags it down.
