yes I am running as root.
On other server which also has 2.2 it shows correct output.
no /dev/mem is not available on both the server, but still one shows correct information.

install it - what distro?

dmesg shows You last output of kernel log (last, hence it may be over hundred lines). Just after starting the system, it shows whole boot messages.

If HT is enabled dmesg  only shows information of Physical processor or logical also?

ravenplCommented:
Logical also(assuming Your kernel supports SMP).
But if You want some info on CPUs, check the /proc/cpuinfo file
