Please no. If we start doing this the lists will grow without bounds.
If we really want to avoit printing "not configured" messages for
devices that attach as non-acpi devices, we should do so by checking
the relevant _CID, i.e. PNP0303 for the keyboard and PNP0F13 for the
mouse. I also would like to add a second table (named
acpi_skip_isa_hids?) for those such that if we ever decide to attach
these devices based on ACPI information instead of isa(4) probing it
will be easy to remove the entries.
The "INT3394" seems to be more than just a system fan control. Google
found me the "Intel(R) Extreme Tuning Utility, Version 4.2 BIOS
Interface Specification" that documents seeral AML methods provided by
this device. Does looks like something that could at least provide
sensor data.
