  * DESCRIPTION: Install a handler for all op_regions of a given space_id.
  *
+ * NOTE: This function should only be called after acpi_enable_subsystem 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 acpi_enable_subsystem.)
