Good, the point of the change was to make tapping the pad work as 
button one.
About the phantom buttons - all Apple trackpads I know report more than 
one button ( two in the PB3400c, four in my iBook G4 ) - the only one 
that's corresponding to a real life button is button one. The others 
are (ab)used for stuff like signalling that there's a finger on the pad 
( the two-button version uses button 2-4 for that, the four-button 
version uses button 5 and reports button four as always down).
The button count reported is bogus and ought to be read as protocol 
revision or something.

So, has anyone ever seen an ADB trackpad that reports something else 
than two or four buttons?

have fun
Michael
