nvidiabl doesn't interact at all with nvidia driver or VDPAU, it only plays with the brighness register (relative address 0xc084) - I got this register address from the nvclock project (http://www.linuxhardware.org/nvclock
) and similar brightness drivers (http://wingolog.org/pub/nvbacklight-0.1.tar.bz2
