Not only should it go into 2.6.22, it's also a candidate for as many -stable kernels as we care to support. It should have been present ever since 2.6.15. It may be that the conditions for triggering that machine check were added fairly recently. Be that as it may, the patch is definitely correct and apparently needed now.
