I doubt that comment is accurate.

Please abstract out the 4e,4f access sequence, so
you can just say  write_sio(0x30, 1);  or similar.

> +	/* Enable superio runtime registers for gpio in pci i/o space */
> +	outb(0x20, 0x4e);	/* device id register */

This write is superfluous as far as I can see.
