Ok, the issue is unfortunately simple here: on the lower-end we
support Intel Conroe Family but your CPU is older and doesn't match
the feature set to be detected as a Conroe CPU.

The cheapest option is trying to understand which CPU your server
mainboard can support (here some hint:
); if you server allows something newer, probably with a fistful of
dollars you could find it refurbished on eBay or similar.
