PS1: 
The Numeric Co-Processor Error Register is an integral part of a 387-compatible FPU (AKA Math Coprocessor), and it's identified specifically by a PNP0C04 EISAID.  While may not used in 64-bit kernels, 32-bit kernels that identify the 387-compatible FPU with ACPI need PNP0C04.  Any ACPI-enabled kernel that wants to know about decoded resources also should be told about the IO space resource being unavailable for other uses.
