Honestly it's not worth the trouble.
I searched for months and spent countless hours trying different things. Its the biggest pain in the @$$. I joined mailing lists , searched www.google.com/linux
, sourcfourge has projects regarding this also none of this helped me.
Finally I just bought a Dsl modem that I could just conect to my nic card this worded like a charm.
I bought my modem from www.sbcdslstore.com
