Actiontec GT701 and WRT54G (Running DDWRT Micro)

I have a Qwest DSL Actiontec GT701 (<i>not the GT701-WG version</i>)
modem and a Linksys WRT54G running DD-WRT Micro.

This situation works, but is not what I want:
Actiontec is plugged into the Linksys WAN port; my computer is plugged
into a Linksys LAN port. The Actiontec supplies a DHCP address and
becomes my gateway. Internet works.

This situation does not work, but after searches has lead me to believe
*should* work:
Actiontec in Transparent Bridging mode, the Linksys set to PPPoE mode
with my username and password in it. The Linksys is never able to
create the connection.

Now I know Qwest doesn't officially support PPPoE and insists on PPPoA
but I set the Actiontec into PPPoE mode and it worked just perfectly so
this leads me to believe that the Linksys should also work in PPPoE but
I just can't get it to work.

I'm open to other suggestions, I basically just want the Linksys to
handle all the finer points (<i>QoS, routing, wireless, security,
etc</i>) and the Actiontec to just pass along the internet. Anything
that'll get me there would be great.

Thanks in advance for anyones input/help
