That, in my opinion, is the single biggest obstacle to someone just 
putting together Rpi or Beagles and doing useful stuff with them. 
There's been so many versions of the OS, with different schemes for 
managing the hardware interfaces.  You search for something, and you 
turn up something from 2 years ago that worked fine on version N-3, but 
then you find a site where someone says, oh yeah, on  N-2 I made it work 
by doing X, but you're on version N.


And, of course, most folks basically are reporting a historical "I did 
this, and this, and this, and made it work for that" - they aren't in 
the software distribution business (or business at all) and it's great 
that they DO report something, but it's a long way from developing a 
generalized approach.
