Google Pacman played locally
 

The code for Google's PacMan javascript game has been archived here:

http://github.com/macek/google_pacman

Included seems to be everything needed to download the source and play the game locally on your N900. There's even instructions for getting the sound to play (the game is javascript, but the music is flash).

I haven't tired downloading it yet, but in the meantime you can point your N900 browsers here to play after Google pulls the code from their main page tomorrow (remember to lock on cursor mode in your browser so you can play with the arrow keys):
