What -march and CHOST settings would you guys use for a CPU that shows
up like this in cpuinfo:

Intel Pentium Dual CPU T2310 @ 1.46Ghz

I'm going ahead with i686 and i686-pc-linux-gnu for now because I want
to get this thing set up, but I'm planning on doing an emerge -e world
when I'm done.

Does this CPU have 64-bit extensions?

It looks like it does.

Does it support sse3?
If /proc/cpuinfo flags has pni
Then I'd go with march=prescott

I'd use "prescott" for this one, as you're using x86 CHOST anyway.

I believe it does, check the flags at /proc/cpuinfo to be sure.
"nocona" would be my choice if possible to create a 64 bits system.

você vê é o que você tem" tão ruim em editores de texto quanto em
mulheres. Não, o programador de verdade quer um editor de texto do
estilo "você pediu, você levou" - complicado, indecifrável, poderoso,
impiedoso, perigoso.

Alright, I'll give nocona a try. Should I be using
CHOST="x86_64-pc-linux-gnu"? And the processor family in the kernel
should be "Pentium-4/Celeron(P4-based)/Pentium-4 M/older Xeon"?

I wouldn't use x86_64-pc-linux-gnu unless you want to break your system. Unless you are starting from scratch 64 bit.

Is there any way to switch to that CHOST after I've already installed
a stage3? If I do get this working with 64 bits, will I be using
amd64 packages even though it's not an AMD system, or would I still be
x86?

Have you already installed a 32bit stage3? If so there is no way to
switch except for a reinstall. AMD64 is for both AMD and Intel 64 bit.

If you click "View processor number details" here:

http://www.intel.com/cd/products/services/emea/eng/processors/pentium_dual-core/340988.htm

it is clearly a 64 bit CPU. Do-over.

Do you think Generic-x86_64 in the kernel?

I think you're safe with that. According the kernel Family 15 is older
Netburst and family 6 is the newer Core micro architectures. You can
tell by /proc/cpuinfo.
