I presume it worked OK on this other Linux system?

Any possibility the NIC in this Linux system (acting as your firewall,
I presume) that's connected to the SpeedTouch home is flaky or bad?

The 'Timeout waiting for PADO packets' indicates to me that either your
linux machine isn't hearing packets from the SpeedTouch Home, or the
Speedtouch Home isn't hearing packets from your Linux system's NIC. 
Given that this modem works with other systems (using the same cables,
I believe?) I'd suspect something with the NIC (either it is faulty, or
you're got something wrong with its configuration - perhaps the IRQ is
specified wrong?), or that you've got the PPPOE software configured
with the wrong ethernet port (you can send PADI packets all day long to
the local LAN, and never get a PADO response).  You can use

pppoe -I eth? -A

(replacing ? with the appropriate number) to see if you get a PADO
response from sending a PADI to a particular ethernet port.
