My processor is not detected intel core 2 duo

When I type

$uname -m -p

I get this

i686 unknown

I have Ubuntu 10.10 netbook remix

but the cat /proc/cpuinfo gives right identification of two processors as below

The problem is with programs that uses more than one core like virtualbox and bitcoin which refuses to use more than one core

Is there anythign wrong or anything that I can do?

My installation is from a live usb iso on a USB
