Well it's not strictly back-compatible, but /proc/zoneinfo is such a mess that parsers will be few and hopefully smart enough to handle this.
btw,
pagesets cpu: 0 count: 118 high: 186 batch: 31 vm stats threshold: 72 cpu: 1 count: 53 high: 186 batch: 31 vm stats threshold: 72
Should the "vm stats threshold" thing be indented further?
Do we need to print it out N times anyway? Can different CPUs have different values?
