Heh I registered to ask this exact same question.
In future (i.e. shortly) will the AGPgart be working for non NVidia cards? I'm about to upgrade my system, but not the gfx card (gf2 mx) so this issue wont effect me yet, but I don't want to get a motherboard that locks me to a certain make of gfx?
Also will it be GPL and be able to be compiled into the kernel? As only having the option of installing it as a module would suck seeing as it would be in use all the time!
Otherwise Ill have little choice other to go with the KT400, which is a shame as reviews and friends experiance indicate its not as good
