Just curious about the other missing IDs: this now supports all Core
microarchitecture CPUs, but only some Nehalem/Westmere ones.

There is support for 0x1a (Bloomfield/Gainestown) and 0x2e (Beckton), but
not for the much more common 0x1e (Lynnfield/Clarksfield/Jasper Forest),
0x25 (Clarkdale/Arrandale) and 0x26 (Gulftown/Westmere-EP).

Shouldn't those be added as well?

When you're there, it probably also wouldn't hurt to fill in the blanks
of some of the older CPUs like Tolopai (0x15) and newer Atoms (0x1c).
