Dual CPU?

I just got my AA1 (Linux, 8GB SSD), and I figured I'd play around with Linpus before I considered putting any other distro on it (and so far I'm pretty impressed!).

One of the things I did was to install gkrellm so I can keep a bit of an eye on what it's up to, but the weird thing is that gkrellm reports 2 cpus, CPU0 & CPU1with activity on both, just like my AMD Athlon 64 X2 desktop running Mepis. I know there were rumors of a dual-core Atom coming out soon- but this has to be a weird glitch right?

cat /proc/cpuinfo also shows 2 cpus:

Weird huh?

 

it is hyperthreading..
