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.
