I don't know why you'd want to use that when the 7i92 is available. You're using a parallel port or serial, which has significant bandwidth and latency issues compared to ethernet. 7i92's only $30 more so I doubt cost is a big factor here.
But, pretty sure it'll work with LinuxCNC. For 7i92, you loadrt HOSTMOT2 which creates HAL pins for all the functions. You do need to use a command-line tool "mesaflash" once to load the hardware bitfile image into the FPGA. There are several bitfiles available, they dedicate specific pins to be stepgens, encoders, etc. You can turn off specific functions and turn them into GPIO, but you can't take GPIO and assign a new stepgen to it, because that involves new FPGA code.
