* DESCRIPTION: Install a handler for all OpRegions of a given SpaceId.
*
+ * NOTE: This function should only be called after AcpiEnableSubsystem has
+ * been called. This is because any _REG methods associated with the Space ID
+ * are executed here, and these methods can only be safely executed after
+ * the default handlers have been installed and the hardware has been
+ * initialized (via AcpiEnableSubsystem.)
