RS sells Raspberry Pi model B board: "Boots from SD card, running the
Fedora version of Linux."

RS is also selling the Debian "squeeze" release on their website. The
ordering number number is 763-1030.

The tutorials I have read on installing Linux on many ARM and MIPS
devices is much more complicated that simply dd image to SD card.

The three articles I cited yesterday clearly discuss that it is the MAC
addresses of nearby wifi devices that are being transmitted. Not just
the AP locations. The articles mention people being able to geolocation
their own router by simply entering the MAC address of their router.
Because of the publicity, Google ceased making this available to the
public. Google, Microsoft, Apple and Skyhook have not ceased doing this
nor ceased making geolocation tracking of MAC addresses available to the
government and information brokers.

MAC Changer requires a script to start up before wifi starts up. The
question I asked yesterday was whether booting up and shutting down the
computer enables wifi before the OS starts up and reenables wifi and
bluetooth after OS shuts down. Meaning, after disabling wifi and
bluetooth in Fedora's network manager, will the processor enable them
when the computer is starting up before the OS starts and disables them?
Will the processor reenable them after the OS shuts off but they
processor hasn't shut down yet? This happened with my i86 MSI and Asus
netbooks. The VIA 8650 netbook does not have a wifi/bluetooth light
indicator on the netbook, so I cannot tell.

MAC Changer spoofs wifi, not bluetooth. I am not aware of a Linux
package that can spoof bluetooth MAC. 

Thank you Gordon for your comments and suggestions. Luke asked me to
cool it so I will now limit my posts. Thanks Luke for explaining this
forum is for developers. I recommend redefining this forum on the sign
up page. Thanks to every one for allowing me to be on this forum as an
user. I will mostly read the threads and try to refrain from posting.
