And you can download a pre-hacked version based on wheezy that can run 
machinery with sub-micron accuracy, far better than the average machine 
can do, as its subject to thermals etc that limit it to perhaps a 
thousandth of an inch in everyday use. From linuxcnc.org today and 
everyday.  Free every day.  I have 4 copies of it running here.  On the 
right board and cpu, this software can send a step pulse to a stepper 
motor driver every 25 microseconds.  Thats 40 kilohertz, not the stepper  
motors top speed, so if you really want to move fast, a 90 dollar card 
can take you to the limits of the opto-isolaters in those drivers at 
somewhere above 200 kilohertz.  Using that card allows one to be a whole 
lot less picky about the board and cpu.
