 To rule one out: can you adjust the brightness if you enable the wmihp(4)
 driver? I.e.
 
 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).
