Try this, it worked on my 3125.
HKEY_Current_USER->Control Panel->Backlight->Values->KeylightTimeout
Mine was set to 15000. I believe it is 15000 milliseconds, ie. 15 seconds.
I set it to 30000 and you guessed it the keypad stayed lit for 30 seconds.
If you aren't familiar with changing registry settings, proceed with caution...you can make your phone into a nice shiny paperweight.
Good luck...
Thanks for the info, That did the trick.
