No idea. Likely some vendor-specific addition to ACPI.

This is the normal parallel port, lpt(4). It can be configured via ACPI
(lpt* at acpi?), but this is commented out in the GENERIC configuration file
(probably for a good reason).

This one handles things like Intel HW random number generator. It should be
supported, but it is handled outside ACPI.

Yes, this is a so-called ACPI fan. People have written drivers for it, but
there is not much to be gained from such dummy drivers.
