Can you explain in more detail what nvidiabl does, and why it's needed, and how it interacts with VDPAU? Thanks.
Complete sources are here: https://github.com/guillaumezin/nvidiabl

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 and https://launchpad.net/~mactel-support-community)
