This switch (opermode=1) is redundant with the current X100P cards, as 
it changes register contents that are specific to the "Global" version 
of the chipset on the card.

The X100P currently out there uses the "USA & Japan" chipset, and thus 
does not achieve the intended result.

The register concerned deals with the impedance presented to the line 
connected to the card - 600 ohms (US) vs various complex impedances used 
in other countries.

For internationalised FXO cards, see Mark's recent comments, in the 
thread "Does Wildcard x100p support BT Caller ID in UK?"
