Does the mounting-system support LGA2011 based Xeon CPUs?

There are two different types of ILM (Independent Loading Mechanism) for Intel’s LGA2011 based Xeon CPUs: Square ILM with 80x80mm hole spacing and Narrow ILM with 56x94mm hole spacing. The Square ILM socket is mechanically identical to the LGA2011 socket for Core i7, so the mounting-system is fully compatible, but it is not compatible with Xeon mainboards that use the Narrow ILM:

Is it a problem that the CPU heatspreader is not covered completely by the heatsinkbase on LGA2011-3?

No. Depending on the orientation of the cooler, 1-2mm at the outer edge of the heatspreader may not be covered by the heatsink base. As the heat is concentrated at the center of the CPU and the outermost parts are irrelevant for heat-transfer, this is no problem at all.
