DSL modem built into the computer? bummer.

Yeah, it's going to be a tricky setup.. mostly because the computer would handle the ppoe connection, so the router would act more as a hub than anything.

So what I think you'll need to do is enable internet connection sharing on the PPOE adapter on your computer.. the LAN cable that is connected to the network will be given an IP of 192.168.0.1 .. if you can, disable DHCP on the router, assign it a static IP of 192.168.0.2, and if you can, point it to a gateway of 192.168.0.1 (your shared computer's IP network).

Basically you want to configure your router so it acts like a hub instead of a router.

Then you can configure a computer to obtain IP's automagically, and it'll pick up DHCP from your DSL-connected computer.

The only caveat is that if others wish to use the internet, your computer will have to stay on, and you'll want to configure the PPOE connection to connect whenever someone tries to hit the internet.

definitely not the preferred way of setting things up.

Preferably, you should call up your internet provider and ask for an external modem (hell, it should be included in the monthly fees), and hook that up into the router instead, and then plug your computer into the router as it should.
