Actually it is the 5220 that does and the 5240 that does not.

The T5220 has the 10GbE circuitry on the CPU.  With the T5240 that was 
displaced by the circuitry for the CPUs to talk to each other, and the 10GbE is 
on another chip.  If you hunt round for the architecture white papers there are 
block drawings.

We have a number of T5220s with the XAUI cards and optical 10GbE SFP+.  Goes 
along briskly especially with Jumbo Frames.

Oh yeah, and if you haven't bought the servers yet, Sun has some with dedicated 
busses for 10Gb NICs.  Haven't played with them yet, but it's definitely worth 
considering.  I want to say the 5240 has them while the 5220 doesn't.
