ich9gen can change the MAC address, so there's no need here.

 	 * That is a datasheet for a later chipset. Word 40H-53H seems (as per this datasheet) to be for AMT. 
-	 * Since libreboot disables and removes ME/AMT, it makes sense that blanking out words 40h to 53h

+	 * Writing over it doesn't seem to cause any harm, since the ME/AMT is already removed in libreboot.
