The commetization of the CPU market was bound to happen eventually. As modern production techniques for chips and FPGA programming start to converge rapidly.
What is the ETA until we get a GNX "GNX is Not X86"? An Open source i386 core that people can run existing applications on? Much like GNU offered a standardized FOSS platform people could run existing Unix workloads on.
There's ao486 already [1] [2]. I seem to recall that there are a few corners where it's not 100% complete/compatible, but it's complete enough to boot Windows 95 and Linux (assuming a Linux distro with 486 support, now an endangered species), and run some classic DOS games/demos. It doesn't run at a speed equivalent to a "real" 486, at least on a cheap FPGA.
