I believe it is only the driver that is the problem, you have a single processor driver installed for some reason (you installed XP with hyperthreading disabled in the bios?), if you update that driver to a multiprocessor driver your other processor should appear after a restart.
To do this go to the "driver" tab in your screnshot above, click on the "update driver" button, select the "install from a list of specific location (advanced)" option and click next, select the "don't search i will choose a driver to install" option and click next then chose the "MPS Multiprocessor PC" driver and click next, follow it through, restart your PC and with any luck your hyperthreaded CPU will pop up in task manager.
You *may* also need to go back into the "System Properties" tab and then go to the "Advanced" tab, click on the "environment variables" button at the bottom, and in the "system variables" menu set the field "NUMBER_OF_PROCESSORS" from 1 to 2. You'll have to restart again. It should do this automatically, but it may not.
Give it a go. if it works, and i believe it should, then it will save you a reinstall. If it doesnt work, then have your XP CD at the ready
