Comparing Apples to Kumquats with the Sun T2

Today Sun announced the SPARC Enterprise T5120 and T5220 servers - the first servers using the new UltraSPARC T2 processor.
Sun compares an SAP SD T5120 benchmark to an IBM System p 570 POWER6 result - but, amazingly, the footnote about this claim is all about the HP rx6600. What's going on here? Maybe the footnote is about the HP system because in reality the POWER6 p570 achieves 1.84 times more performance than the T5120.(1)
Sun compares a T5220 Notesbench result to the IBM System x3650, a configuration that is half the number of cores and more than 2.6 times less memory.(2)
Sun compares other vendors' power configurator values and maximum power values to Sun's actual power measurements from their benchmarks. Not exactly apples to apples is it ?
Not even Cortlands vs. guavas.
