I believe this is not specific to the P52 but simply the keyboard
version that includes a numpad. I only have the P52, but looking at
photos of e.g. the T570 and T580 the keyboard looks identical there.
On a different note, these keyboards also have "=", "(" and ")" keys
above the numpad. These keys emit the key combinations required for a
US keyboard layout on the P52 I have. I do believe there is a way to
set the keyboard layout through ACPI which I suspect changes the
emitted keycodes to match the expected values for other layouts.
Unfortunately supporting that seems quite involved.
