Pismo trackpad "tap" activation with YDL 3.0?

[Steve]

I just got my YDL 3.0, and I can't seem to get the trackpad to tap-click 
on my Pismo/Firewire Powerbook. Tried using the suggestions for YDL 2.2 at

http://www.yellowdoglinux.com/support/solutions/ydl_general/mouse_buttons.shtml

but fiddling with my /etc/sysconfig/mouse doesn't seem to work.

Another alternative is to tell my system to execute:

/usr/bin/trackpad tap

on every startup, but this seems overly complex for a simple and common 
feature for laptops (why isn't this configured on the install?). Oddly, 
I could use the trackpad to tap for mouse clicks during the install, but 
I can't do it AFTER the install.

Anybody else having similar troubles?
