Keyboard and Elan trackpad nonfunctional on Acer C738T (Chromebook with hacked UEFI firmware)

Description

Running the nightly build from Dec 19, 2022 - Walter (Revision hrev56652), x86_64

This is odd hardware - An Acer C738T Chromebook ("cyan") with hacked Coreboot/UEFI firmware flashed onto it. That said, it's made of mostly Intel "stuff", with components used in other laptops. The keyboard, trackpad, audio and storage don't work - but the keyboard and trackpad are really the more important aspects at the moment and the reason/scope for this ticket. The trackpad is made by Elan and appears to be I2C attached, and the keyboard seems to be some variant of PS/2 despite being a raw matrix going to the motherboard.

The output of "listdev -d" outputs the device tree.

I noticed a Network preferences crash in your log. Looks like https://cgit.haiku-os.org/haiku/tree/src/kits/interface/MenuItem.cpp#n453 fSuper is possibly NULL. @waddlesplash can Draw() be called without fSuperItem?

@waddlesplash can Draw() be called without fSuperItem?

I don't know how that would happen. fSuper can only be NULL when the item isn't in a menu, i.e. when it isn't going to be drawn, to my knowledge. Perhaps there's a race between removal and drawing...
