GPIO use

I have some difficulties to reach GPIO pin through Panasonic 100-Pin connectors with an Linux OS.
The main problem concern is that the mapping provided does not contain the port numbers GPIO side OS (Ubilinux). After some tests, it turns out that the GPIO ports on the Linux side start at 318 and then dispatch "randomly" (it's over 500). It is therefore difficult to connect the pin 46 (GPIO25 / PWM0) with the corresponding port on the Linux side. It is necessary for us to interface with a driver.

Could you help us to use GPIO port with linux?
