On the http://chdk.wikia.com/wiki/Talk:Porting_the_CHDK page Eric has sucessfully downloaded the firmware already. I just copy the talk here: The firmware is available at http://www.datenschleuder.eu/get_00dffa1b5da74c038e1d548055d37531.html and the password is "a504". You can download that at http://rapidshare.com/files/70092983/ps_a540_100B.7z.html as well.
