+2c) Probing the cards with broken PCI subsystem ID
+--------------------------------------------------
+There are some TwinHan cards that the EEPROM has become corrupted for some
+reason. The cards do not have correct PCI subsystem ID. But we can force
+probing the cards with broken PCI subsystem ID
