Or the early in-order Atoms, I believe.

Is VIA affected by Meltdown? I don't use their CPUs but I noticed the existing patches to make the workaround conditional contain "if (c->x86_vendor != X86_VENDOR_AMD)", not "== X86_VENDOR_INTEL".

Of the various VIA cores released over the years, only the Nano series supported out-of-order execution. (And 64-bit support...)

Meltdown? No idea. But Spectre, probably.

How does one tell? I do have a Nano U3500 chip here. Can any of the PoCs that are already public check that reliably?

The whitepaper [1], mentions speculative instruction fetches and decoding no word on speculative execution and data loads.
