Here we go:

$ sudo grep . /sys/bus/pnp/devices/*/id
/sys/bus/pnp/devices/00:00/id:PNP0a08
/sys/bus/pnp/devices/00:00/id:PNP0a03
/sys/bus/pnp/devices/00:01/id:PNP0200
/sys/bus/pnp/devices/00:02/id:INT0800
/sys/bus/pnp/devices/00:03/id:PNP0103
/sys/bus/pnp/devices/00:04/id:PNP0c04
/sys/bus/pnp/devices/00:05/id:PNP0c02
/sys/bus/pnp/devices/00:06/id:PNP0b00

/sys/bus/pnp/devices/00:07/id:PNP0c02
