If the processor are not on the HCL, then they are not supported.
If they work, thats another question....
That begs the question, how often do they update the HCL when new processors are introduced?
To be exact: Nehalem is on HCL. IBM x3650 M2 with Nehalem is not yet on HCL.
I think there will be no problems.
