What's Intel Atom support like these days? I remember they used to be
a little weird. Are they handled pretty much like any other x86 chip
now or are some things still unsupported? Are they capable of handling
pf on a saturated 100-base-t connection? How about gig-e?
There's a huge range of Atom processors. Some are 32-bit only single-
core, there are models which are 64-bit capable and multi-core. There
are
a wide range of clock speeds, cache sizes, and bus speeds.

I have an Asus 1005HA netbook with an Atom N270. As it's a workstation,
I can't speak to router performance. But the processor: single-core,
32-bit only, has always appaered to be a "normal" x86. I just can't
disable
HT in the BIOS.
I don't have a recent dmesg available as I don't have the device with
me at the moment. Here's an excerpt from one I'd sent to misc@ a couple
of years ago that I just grabbed from marc.info. This one is GENERIC,
I normally use GENERIC.MP -- though to be honest, I do not perceive
a performance delta between the two.
