Or even better, what one should look for in the output of, for example, "cpuctl identify 0". Since I didn't exactly know, I made some guesses and assumed that my cpu ("Intel(R) Core(TM) i3-2120 CPU @ 3.30GHz") did't have the required features (it is from 2009 or so). But this thread inspired me to modload nvmm, which actually helped, so I found out that it even works on this cpu. Of course I immediately tried it with Haiku (the BeOS clone) from https://download.haiku-os.org/nightly-images/x86_64/ and I got mixed results. Once it manages to boot it works fine and nicely fast (much better than without nvmm), but quite often it crashes into its kernel debugger during the first 10 seconds of booting, with different messages (I have seen "General Protection Exception" and "ASSERT failed ... fCPUCount >= 0").
