Hello,
This is patch against 2.4.21-rc2 adding Nvidia Nforce1/Nforce2 AGP chipset support.It worked very good on 2.4.21-rc2-ac3. I found this patch here : http://etudiant.epita.fr:8000/~nonolk/nforce-agp.diff

Don't know who ported it from 2.5.69, however I know this address above belongs to author of this patch
