relevant code is in ultralcd.cpp

for literal starters (haha), try Configuration.h as per:

$ grep SPLASH *
Configuration.h:#define STRING_SPLASH_LINE1 SHORT_BUILD_VERSION // will be shown during boot in line 1
Configuration.h:#define STRING_SPLASH_LINE2 WEBSITE_URL // will be shown during boot in line 2
