Version for Sempron 3600+

[bsd10]

Should I use amd64 or i386 for this cpu?

CPU: AMD Sempron(tm) Processor 3600+ (2009.13-MHz K8-class CPU)

The documentation says to use amd64 for newer Semprons, but I'm not sure if this one qualifies.

This CPU should support AMD64 instructions.

Agreed, I believe all K8 procs are amd64.

Features shown right after the CPU in dmesg(8) should identify whether it supports amd64 , but I can't recall which.

LM stands for Long Mode, meaning 64-bit, AFIK.
I don't know, but it seems that NX is pretty specific to 64-bit ( I don't know that it has to be, but I also don't know of any i386 chips that implement it).
