But, there are a NUMBER of RT patches and options for various Linux kernels. Rtai, RT-preempt, Xenomai are the first ones to come to mind. RT-preempt is included/available for most kernels, but doesn't give stellar RT latency. However, it is probably good enough for most hardware-assisted motion control systems.
