I solved the problem!!!

It appears that the edac drivers prevent intel_agp from detecting the
AGP.
After tying in:
modprobe -r i82875p_edac
modprobe -r edac_mc
modprobe -r fglrx
modprobe -r intel-agp
modprobe -r agpgart
modprobe intel-agp
I got the message:
agpgart: Detected an Intel i875 Chipset.
agpgart: AGP aperture is 128M @ 0xe0000000
Which I hadn't seen before. 3d acceleration works again.
Now I wonder what this edac is?
