It may not, I have just always disabled it on dialer links as a habit. It
makes sense that it shouldn't since the dialer-list defines layer 3 traffic
only. You could always put an access-list on the dialer interface permitting
all traffic with the log statement to see exactly what is trying to get
accross the line. It will output to the console if you are consoled in. That
may help you to see what is bringing the line up.

Can somebody tell me how come CDP may bring the line
up? As you know, it works only in layer 2 as said
before. Your dialer-list works at layer 3 & 4 only.
Did I miss something? :-(
