Yes. There is backlight notification mod for our phone. However, I tried several versions(10-32seconds) and could not get the backlight to turn off until I cleared the notification. I believe it only works with certain kernels and ROMs.
I have that installed, it just keeps the lights on longer for the softkey buttons.
What I would like to see is one of the softkeys like home pulse with the screen off when a new notification arrives, like the nexus one trackball notifications.
