kinda curious, uname -a said "Linux dr02g 2.6.18-4-686 #1 SMP Wed Feb 21 16:06:54 UTC 2007 i686 GNU/Linux".

This is not a SMP kernel, not a real one or something different?! dpkg said, the installed "kernel" is "linux-image-2.6.18-4-686" and "linux-image-2.6-686" (no kernel-image-* is installed)

~$ grep SMP /boot/config-2.6.18-4-686
CONFIG_SMP=y
# CONFIG_X86_BIGSMP is not set
CONFIG_SUSPEND_SMP=y
CONFIG_X86_FIND_SMP_CONFIG=y
CONFIG_X86_SMP=y

The 686 kernels are SMP for some time now.

The linux kernel packages in etch and above have been renamed to avoid
conflicts with non-linux kernels like freebsd.

HTH,

Well, I'm glad to see that I'm not the only one that was confused by the
renaming of kernel-image to linux-image. That one really had me going
for a while.

Regardless of all the kernel naming confusion, I guess this comes down
to the fact that your kernel supports SMP. This means it supports
multiple processors, multiple cores, and hyper threading. Since you are
only seeing two processors and not four, I don't think your CPU is hyper
threaded.
