MFC r320743:

Fix drivers that assume ticks starts at zero. These drivers all have logic
similar to "if (ticks > localvar+interval) {localvar=ticks; ...}" where
localvar is initialized to zero.  Ticks is initialized to a negative value
since r278230, and that leads to these if statements never being true.
