If you actually read the PDF document he refers to in his brilliant insight, you'll notice that Hyperthreading is only turned off on the dual processor systems. It is specifically turned ON for the single processor tests.
I don't think they were really trying to mislead anyone on the speed of the new Power Macs by decreasing the speed of the Dells. If they had been trying to do that, they could have easily left everything the way it was on the Dell by not updating the Red Hat software, or they could have run the tests under Windows.
What I saw in the G5 tests looked like optimizations more than anything else. They put in a couple of speed switches, similar to -O3 in that it would use memory less efficiently but make it run faster.
As with any benchmarks, YMMV.
