Never mind, I took a look at the LinuxCNC hardware page for the answer.  These 
boards are pretty expensive, almost a thousand bucks for the Servo-to-Go ISA 
card.

Seems like the BeagleBone and a custom cape with some high powered MOSFETs 
would be more cost effective (ala Replicape), but if there is no hardware 
abstraction layer to separate the gcode generation process on LinuxCNC then it 
doesn't seem like that would be a feasible endeavor.

What's a typical hardware configuration for LinuxCNC then?  I see a lot of 
mention of x86 Atom machines being used.  How are you interfacing LinuxCNC with 
high powered MOSFETs to drive servos for example, especially if USB is not an 
option?
