Yes, it is apparently a Nocona model, this is part of the dmesg:

I would love to, especially because the tests will complete faster, but
I currently do not have access to physical machines of that class.

Normally I do performance tests on the FreeBSD reference machines, but
since these tests require booting with a custom kernel (and preferably
root access + remote console), I cannot use them.

So if somebody can offer such a machine (for a limited time only, a few
days most likely, 1 week maximum), it would be great.
