Great, so acpi_listen is reporting the brightness key events correctly:

video LCD0 00000087 00000000
video LCD0 00000086 00000000

if the video module is loaded. So I suppose something is interfering
with the acpi module at a lower level? Is there anywhere I can look
for debug messages regarding this?
