* The ralinkwifi driver links now.

Browse Source 
* There is firmware needed, which can be distributed with Haiku:
  a) Get the firmware from www.ralinktech.com -> Software -> Linux
     -> Firmware RT2501(RT2561/RT2661)
  b) Extract the three binaries to /system/data/firmware/ralinkwifi/
  c) Rename them by removing the '.bin' ending and append fw instead
     (e.g.: rt2561.bin -> rt2561fw)
