Subject: [PATCH] * The ralinkwifi driver links now. * 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)
