Hardware notes: Acer C720 Chromebook

To get Linux running on the Acer C720 Chromebook, I had to do the following:

0. first I tried ChrUbuntu - it installed a 64-bit environment with 
   kernel 3.13, but the system had problems resuming from sleep.

1. install Bodhi Linux with E17 from here:

   (this installs a 32-bit environment with kernel 3.11 and a slightly outdated 
    Bodhi Linux based on Ubuntu 12.04 -- however, it has one big advantage: 
    IT WORKS)

2. to prevent packet loss, I had to disable hardware encryption in the ath9k 
   driver based on advice from here:

   - create a file:  /etc/modprobe.d/ath9k.conf
   - enter the following into that file:  options ath9k nohwcrypt=1
   - reboot
