Bon... J'ai au moins réussi à activer l'AGP avec agpgart, en mettant Option "NvAGP" "2" dans /etc/X11/XF86Config-4, et ça va quand même beaucoup mieux maintenant.
Maintenant, un cat /proc/driver/nvidia/agp/status me donne :
Status: Enabled
Driver: AGPGART
AGP Rate: 4x
Fast Writes: Disabled
SBA: Disabled
Mais je voudrais tester avec nvagp, alors si un éclair de génie vous traversait l'esprit...
