To rule one out: can you adjust the brightness if you enable the wmihp(4)
wmihp* at acpiwmibus? # HP WMI mappings
This is commented out by default on GENERIC kernels. Be sure to comment out
the alternative in turn:
#hpqlb* at acpi? # HP Quick Launch Buttons
Otherwise we'll revisit this once the code for ACPI display devices has been
merged (hopefully soon).
