Neither is model 31. Which tells us what? That the page isn't up-to-date? After all model 31 is referenced in SDM Vol 3 appendix B.4, and model 45 in the same document appendix B.7. They're also both in table B-1 of the SDM doc changes (rev 032 from May this year). Or are you saying the SDM is incorrect? At least this answers the question raised in http://lists.xensource.com/archives/html/xen-devel/2011-11/msg00411.html - 0x2E and 0x2F are supposed to go into the Nehalem/Westmere group then for cpuidle purposes.
