- *	This driver has only been tested with the Consumer IR
- *	port of the ITE 8172 system controller.
- *
- *	You do not need this driver if you are using the ps/2 or
- *	USB adapter that the keyboard ships with.  You only need 
- *	this driver if your board has a IR port and the keyboard
- *	data is being sent directly to the IR.  In that case,
- *	you also need some low-level IR support. See it8172_cir.c.
