I probably won't add it to the project proper, and I can't guarantee you won't run out of resourses if you use it, but if you want to tinker I think after the "lastactivity" line might work:
i.e.
Code:
if(lastActivity == nil){//wake up!!!
LCD::gotoXY(0,0);
LCD::print(getStr(PSTR("OpenGauge ")));
LCD::gotoXY(0,1);
LCD::print(getStr(PSTR(" MPGuino v0.74")));
...
maybe make a splash function to do the lcd stuff and call that instead
