[Linux-libre 5.15 -> 6.8 or 6.17] laptop lid sensor not working

Linux-libre 5.15 @ T11 suspended the system when the lid was closed. Upgrading for HWE 6.8 within T11 made that stop working. No solution worked from https://www.kernel.org/doc/html/latest/firmware-guide/acpi/acpi-lid.html :

button.lid_init_state={method,open,ignore}

in GRUB cmdline with update-grub and reboot.

The issue continues in 6.8 @ T12 and HWE 6.17 also.

Running 6.17 and closing the lid just after sleep 5...:

$ cat /proc/cmdline
BOOT_IMAGE=/vmlinuz-6.17.0-20-generic .... button.lid_init_state=method
$ sleep 5 && cat /proc/acpi/button/lid/LID0/state 
state:      open

$ cat /proc/cmdline
BOOT_IMAGE=/vmlinuz-6.17.0-20-generic .... button.lid_init_state=open
$ sleep 5 && cat /proc/acpi/button/lid/LID0/state 
state:      open

$ cat /proc/cmdline
BOOT_IMAGE=/vmlinuz-6.17.0-20-generic .... button.lid_init_state=ignore
$ sleep 5 && cat /proc/acpi/button/lid/LID0/state 
state:      open
