Seems I am the most fortunate, for me adding 'options thinkpad_acpi brightness_enable=1' to /etc/modprobe.d/options helped, it made brightness changing working and also the Gnome brightness indicator non laggy. For the record I have an R61-8935. The only glitch remaining is that Fn+End changes the brightness down in around twice as big steps as Fn+Home up, more precisely it requires 8 steps from 100% down to 0, and 15 steps from 0 to 100%.
