The assumption is made that the community would prefer that this change be a UV specific quirk, as opposed to automatically adding the EFI memory map entries whenever more then 128 E820 entries exist. If this assumption is incorrect, the patch can be changed to check the number of E820 entries rather than for whether or not the system is a UV.
