The standard ACPI crap doesn't work - if I don't boot with
acpi_backlight=vendor I get a blinding max level backlight which cannot
be modified by pressing the keys.
The thing is, with "acpi_backlight=vendor" and thinkpad_acpi loaded
with "brightness_enable=1" the backlight actually gets modified nicely
so thinkpad_acpi supports it after all. Maybe the simplest fix is for
thinkpad_acpi to shut up about this button when brightness_enable is set
and maybe when the model is x230?
Hmm.
