@Chris Jepsen, I can't add as proposed by silvan, since I don't have an HP but a Sony laptop. I had to add the lines I proposed (or maybe I made a mistake). The file
/usr/share/hal/fdi/information/10freedesktop/10-laptop-panel-hardware.fdi
seems to tell the system that brightness is controlled in hardware or is not when "acpi video module reports it handle the events, but it don't work on this machines".

So I must simply be in the case where brightness is not controlled in hardware, and the software control does not work for another reason.
