After reading the related bug 1853277 for the Thinkbook IML variant, I
see that the elan touchpad is not visible on the i2c bus:
$ cat /sys/bus/i2c/devices/*/name
Synopsys DesignWare I2C adapter
i915 gmbus tc6
DPDDC-A
DPDDC-B
DPMST
SMBus I801 adapter at efa0
i915 gmbus dpa
i915 gmbus dpb

With this kernel patch, the touchpad seems to be recognized, but it will
not function:
My system has this directory:
/sys/bus/acpi/devices/ELAN0634:00
status is 15, but touchpad is unresponsive.
