Not sure what is the scenario you want to use it for. For low level 
access you can use kernel input subsystem directly

see e.g. evkey.c [1] and its usage in bootmenu.sh [2]. Just beware that 
different devices have different device names and key events still go to 
the rest of the system.

For playing nice with the system using powerlaunch [3] is indeed better. 
I am not aware of 770 version (the author [4] has/had N800) but the 
source is here [4]. Maybe it could build fine at least in OS2007 hacker 
edition.
