run-parts uses a set of simple regular expressions to ignore both backup 
files and dpkg conffile leftovers.  This is the relevent code from the 
schroot run-parts class:

  bool match = false;

  static regex lanana_namespace("^[a-z0-9]+$");
  static regex lsb_namespace("^_?([a-z0-9_.]+-)+[a-z0-9]+$");
  static regex debian_cron_namespace("^[a-z0-9][a-z0-9-]*$");
  static regex debian_dpkg_conffile_cruft("dpkg-(old|dist|new|tmp)$");

  if ((regex_search(name, lanana_namespace) ||
       regex_search(name, lsb_namespace) ||
       regex_search(name, debian_cron_namespace)) &&
      !regex_search(name, debian_dpkg_conffile_cruft))
    match = true;

You could easily adapt these expressions and logic (if needed,
they are very general) for use by modprobe.
