I have agpgart compiled into my kernel and it works fine. Works better
than with the NVidia nvagp. However I have a Geforce II GTS, and it took
a few tests. Suggest you compile agpart as a module, then experiment
with using agpart and nvagp (Option "NvAGP" 0,1, or 2 I believe).
I have a Via Apollo Pro KT133 chipset and 4x works fine, but the above
poster is correct there have been problems reported.
