Touchpad and I2C not working

Description

I'm running Haiku on a Samsung laptop, model 750-XED. It loads fine, but the touchpad isn't working. After some digging, it seems is a problem with the I2C bus, as it throws an "PCI BAR not assigned" error and the syslog show the BAR is zero. I attached the syslog. (For the record, the last boot attempt, in the said computer, starts at line 2728. The previous logs are from an unrelated machine) Windows says the HID device is attached to Alder Lake PCH Serial IO I2C Controller #0, vendorID 8086, deviceID 51E8.

I don't know if this helps, but this is what Linux reports for the I2C Controller.

Yes, this is a known problem and the root cause is bug #3
