This is not good news!

All I can say is that I've been running EMC on a milling machine
for about 2 years, with excellent results and reliability. I am using
a 100 MHz pentum classic, 32 MB of EDO DRAM, a 1.2 GB
SCSI hard drive, all on an Intel ATX motherboard. I am still
using a system based on Red Hat 5.2 Linux, with the old
RT patch set for that 2.0.36 kernel.

I really don't understand the desire to break with what has been proven
to work to forge into VASTLY uncharted territory. And, trying to
bring up the RT patches on non-Intel architectures just to do a
machine tool conversion is going SO far afield as to be ludicrous!
