For anyone that’s been missing the BLN (backlight notifications) from the Google Nexus One on the new Nexus S, there’s a nice little custom kernel now available that will light up your softkeys instead. This comes from the development community at XDA. Here’s video proof.
If you’d like to give it a try, you can download it here. Also, there’s been some users who have not been able to get it working on their devices, so if you try it and it doesn’t work out, let them know by commenting on the thread link below.
