root at z:~ # ls /boot/kernel/acpi*ko
/boot/kernel/acpi_asus.ko       /boot/kernel/acpi_hp.ko         /boot/kernel/acpi_toshiba.ko
/boot/kernel/acpi_asus_wmi.ko   /boot/kernel/acpi_ibm.ko        /boot/kernel/acpi_video.ko
/boot/kernel/acpi_dock.ko       /boot/kernel/acpi_panasonic.ko  /boot/kernel/acpi_wmi.ko
/boot/kernel/acpi_fujitsu.ko    /boot/kernel/acpi_sony.ko

The laptop is DEll precision 3250,
so not sure if any of these modules
apply. Perhaps acpi_wmi?

Yes, I've looked at these, but as you say,
this is just making sure the touchpad device
can be used with some extra capabilities.
But I cannot even get the basics working.

Thanks anyway
