Input: pmouse - move Sentelic probe down the list
Sentelic probes confuse IBM trackpoints so they stop responding to TP_READ_ID command. See: http://bugzilla.kernel.org/show_bug.cgi?id=14970 Let's move FSP detection lower so it is probed after trackpoint and others, just before we strat probing for Intellimouse Explorer.
