Another even smaller sledgehammer is to ask the drivers to use EVIOCGRAB on
the device node. This should work fine for those tests using a specific
device but will turn parallel tests testing hotplugging into a game of dice.

We can tag the device with anything, but this will apply after creation
only - at which point it is already added by the server.

Other than that - no better idea so far.
