Little brightness issue on Pavilion dv2889

[David DEMELIER <demelier.david%gmail.com@localhost>]

Hi,

I'm running NetBSD 5.0 Stable on my Pavilion dv2899, the acpi works
almost perfectly (battery time, temperature works fine) But I just
have a little issue with the brightness, in fact if I want to
decrease/increase my brightness using the fn keybinds it doesn't
change immediatly, I need to go in a tty and come back to X (seems
like `refresh' the screen).

This is the dmesg output
