I'm the OP and Ubuntu 11.04 continues to work for me with:

However, prompted by Dimitry's comment I had checked the drivers and had found that in this fresh Ubuntu 11.04 installation, Jockey had installed the nvidia-173 drivers by default. They worked fine, but I decided to try the nvidia-current (which I had used before with the previous install) and used Jockey to switch. This made Jockey install a new xorg.conf without the EnableBrightnessControl option. On reboot the keyboard brightness keys did therefore not work, I had to add the option to xorg.conf again and restart X.
