Ok, my final suggestion then is to try using 1919905652 instead of 
'root'. On my system (PowerPC 32-bit), that number is the integer 
interpretation of those four chars. I'm not really sure if that how this 
works... I don't really know C all that well. Also, if you are on an 
intel machine, you may want to figure out what kComputerIcon evaluates 
to yourself.
