Finding hardware revision
NOTE! The string found in /proc/cpuinfo IS NOT A RELIABLE INDICATOR OF WHICH HARDWARE YOU HAVE! [citation needed -- for shipping A5 and A6 PCBs it should be perfectly reliable]
You will need to login via USB Networking or otherwise SSH into your FreeRunner, and find the hardware revision as follows:
