So I was following another one of Derek Molloy's videos on using the BBB, 
this time on GPIO's:
Beaglebone: GPIO Programming on ARM Embedded 
Linux<http://www.youtube.com/watch?v=SaIpz00lE84&lc=JdlhUeEi_0kNlx7vRz8dghZ_nQ8L88nz0CacbSxxovw>

Around 8:00, he goes into a directory called omap_mux in the 
sys/kernel/debug directory, but I don't see it in my BBB. I've Googled 
around and found that a lot of people have this problem, but couldn't find 
a real solution. 

As far as I understand this directory is supposed to have all the pins for 
GPIO. Is that correct? How can I get around this to access GPIO? Thanks for 
any help with this! :-)

FYI, when I run *uname -a* I get the following output:
Linux beaglebone 3.8.13 #1 SMP Wed Sep 4 09:09:32 CEST 2013 armv7l GNU/Linux
