What is the processor family for an Intel T2080?

Question

Hi everyone, I'm compiling my own kernel and I'm stuck on the part regarding processor family. I got a weird sort of CPU. It's an intel pentium dual core T2080. It's not a Core 2 Duo or any of that. According to wikipedia, the model name is 'Yonah' and it is based off of Pentium M. However, the CFlag article on the wiki recommended the Pentium 4 option for all Pentium Dual-Cores. I also got some other varying responses on IRC, including Pentium MMX and Xeon Duo Core. Anyone have any idea what processor family I should be using here? This is my /proc/cpuinfo output:

I know, but what does Yonah go under? There is no 'yonah' option, moreover, it isn't listed under 'help' in any of the processor families. These are my options:

Yonah is the code name for that specific core. Core Duo and Intel Dual-Core are brand names to sell the processors under.
A Pentium Dual-Core may be a Yonah (Core family), Merom (basically Conroe, Core 2), or Allendale (Core 2).
A Core Solo or Core Duo will only be Yonah. The Pentium Dual-Core variant just has half the L2 cache.
A Pentium 4 could be a Willamette, Northwood (A,B,C), or Prescott (D,E). The Prescott has had many revisions of other code names, and was a significantly chip from the previous Pentium 4 CPUs (initially, it was crap; but, after a few revisions, and compilers targeting it, it was OK). I forget where Cedar Mill fits in there, if at all, to consumer chips (it's basically, "we can fit more stuff on the Prescott die--cheap! Let's do it!").
A modern Celeron could be a Willamette, Northwood (as crappy as Deschutes, FYI), Prescott (D), Cedar Mill (D), or Allendale (Dual-Core).
There's no reason to give a single CPU its own tuning or architecture feature set, unless it really needs it. The Pentium-M sucked in many ways, so it needed it (they're not bad chips or anything, but were rushed out, due to AMD gaining ground in Notebooks). All of their chips since were designed to take the same kind of code as the Prescott, including the Atom, which is about as far away from the Prescott as you can get.
