Maybe. The two SFF mounted on most rev B are connected to ports which only do SGMII, not 1000Base X. They tend to work by chance, and as such, i've never taken them seriously.
If i remember correctly, you modified your board, moved the SFF over to the normally unpopulated slots, and removed a resistor. That setup then has the SFF connected to the 6352, which can do both SGMII and 1000BaseX.
It could also be that the 6352 does have pass through from the PCS to the MAC, where as the 6390 does not? The 6390 is much more capable, having 2.5G and 10G support. The SERDES registers are very different, C45 vs C22 of the 6352.
