That seems more architecturally neutral. I like it.

I don't know. Maybe some might. Perhaps there is some better name that is architecturally neutral, but still has a numerical rather than boolean value?

I sincerely hope that it is the same value across the system. Currently the BIOS setup option to enable SNC doesn't have per-socket choices, it is just an all-or-nothing choice. "2" isn't the only choice for number of SNC nodes on a socket. "4" is (or will be) a choice.
