How is the OS supposed to react to them?

Issue stylus insert and remove messages which can then be mapped to scripts

details? usecase?

echo "0 blink" > /proc/acpi/ibm/led

Currently fails with :

[ 104.727409] ACPI Warning: For \_SB_.PCI0.LPCB.EC__.LED_: Excess arguments - needs 1, found 2 (20130328/nspredef-272)

Blinking leds are a simple way to do many things (ex: indicate successful system boot on a screenless computer)

Some people here would call it a feature.

I do not call non working hardware a feature, especially if linux drivers exist.

Letting users be able to use or not use their hardware in anyway they chose is a feature.

TPM is just a glorified way to store hashes, but it could have some uses say.

Not true. Just do the same changes to the corresponding *.asl files in
coreboot repo and send the patch to gerrit. Other than a layer of
preprocessing, it's exactly the same code as you got from disassembly.

I did not realize that and thought it interacted with static defines - and so I would have to create a coreboot version-specific DSDT. Thanks. I will see if I can have that work.

For the ACPI Warning about SystemIO, I have no idea though.
