FWIW #1 - the port of NetBSD to this ARM platform has already had some cursory
looks from a couple of developers. It wasn't given a raving review.
FWIW #2 - I have two of the x86 "sister" devices (TS-5400) for a
proof-of-concept project. They run OpenBSD fine, but some small hacks for A20
and keyboard controller are required in the boot code in order to get the
devices going. Bridged throughput topped out about 5Mbit/sec between the two
on-board dc devices. For a -40C rated device, they are reasonably cheap.
Whether or not I can successfully get (or, really, want to get) PPP working
over RS-485 over control cable is another question entirely...
