The wiring I used to get the rfm12 module working on the Ben NanoNote, and for which the provided kernel patch can be used without further adjustments, is the following.

GPIO | PIN on SD port | PIN on module | purpose / description

|================|===============|============================

108 | D12 (1) | MISO / SDO | SPI: master input slave output 109 | D13 (2) | nIRQ | interrupt 104 | D08 (3) | (unused) | (unused) X | VDD (4) | VDD | power 105 | D09 (5) | MOSI / SDI | SPI: master output slave input X | VSS (6) | GND (1+2) | ground 106 | D10 (7) | SCK | SPI: clock 107 | D11 (8) | nSEL | SPI: chip select

There needs to be a resistor (10-100kOhm) between pin FSK (if used) of the rfm12 module and VDD as pullup – however when just using ASK it isn’t needed anyway.
