Try this:

* Copy /usr/libexec/navicore-navigator to your computer
* Use a hexeditor (I used Notepad++ with hex editor plugin)
* Open navicore-navigator with hexeditor and start voodoo: search in file /sys/devices/platform/wlan-omap/cal_mac_address and change this to /home/user/./././././././././././././.oksikokos
* # cp /usr/libexec/navicore-navigator /usr/libexec/navicore-navigator.bak # backup original navicore-navigator
* Copy hexeditted navicore-navigator to /usr/libexec/navicore-navigator # don't worry you have a backup
* $ touch /home/user/.oksikokos
* $ cat /sys/devices/platform/wlan-omap/cal_mac_address > /home/user/.oksikokos
* $ HWADDR_wlan0=60:46:04:60:46:04 export HWADDR_wlan0
echo $HWADDR_wlan0 >/home/user/.oksikokos
