Hi this bug affects also my HP DV6-6030el after a bios update 2 days ago. The previous one was F.06 version, the new one is F.1A. Can you check your bios version please?
There is no way to control the backlight, it is set at maximum level. I 'm running with ubuntu 11.04 and kernel 2.6.38-11-generic. I tried also with 2.6.39 rc4 without improvements. The same result with option acpi-backlight=
If I try to change the backlight in the kernel log I fing this message:
Aug 8 01:32:08 Houston kernel: [ 1640.031413] atkbd serio0: Unknown key pressed (translated set 2, code 0xab on isa0060/serio0).
Aug 8 01:32:08 Houston kernel: [ 1640.031416] atkbd serio0: Use 'setkeycodes e02b <keycode>' to make it known.
Let me know if you need more information.
Thanks
