Ok, now I catch it. It's actually my own written script, which is 
executed at init a bit after X starts. It does a couple of 
"setkeycodes". So now the scenario is very clear: X starts, init script 
do setkeycodes, resume/suspend, X detect a difference in keymaps and 
disable the device.

BTW, I haven't really found info about this: what does setkeycodes? It 
does not work on a specific device, but still it changes keymap of some 
specific devices. Does it change only the current devices which have 
keys? Whenever a new input device appears, all the setkeycodes should be 
re-executed?
