Looking further into it, I can see in /var/log/Xorg.0.log that there are significant number of entries about my keyboard beigin disconnected/connected. But there are are some serious weirdness there. For example how in the world does it come up with idea to set various mouse option on _keyboard_? I use trackball with mouse wheel emulation, but it seems that it adds those option on keyboard somehow, which is also weird. How it decides to reconect keyboard? I doubt this is any hardware issue, because nothing changed from when I had 10.04, and it was working well then.
