I thought the KT400 chipset (at least) had been backported to 2.4.21 ?

I'm not experiancing any technical problems. The nvidia /proc interfaces are
reporting that I'm running at agp 8x, and I have full hardware acceleration
enough to play games like Unreal Tournament 2003 quite fast (~50fps), its
just that agpgart cant find my aperature size...

I just tried my vendors (mandrake) 2.4.22 kernel and I get exactly the same
output.
