You still have to carefully pick the hardware for LinuxCNC to run well, but at least it IS available and at a reasonable price. Still, the parallel port is a horror, and whatever flavor of PCI you choose involves some difficulty in interfacing chips. The Beagle has pretty easy to use GPIO pins, and maybe the newer boards will have better performance that the original.
But, the glacial pace of getting an RTAI patch for these chips is pretty worrisome. The Beagle Board is a very popular platform for developers, but at this rate the LTS kernels will be obsolete before the RTAI patch is even available. That is not an acceptable path, either.
