Looks fine, now I got:

agpgart: Found an AGP 3.0 compliant device at 0000:00:00.0.
agpgart: Putting AGP V3 device at 0000:00:00.0 into 8x mode
agpgart: Putting AGP V3 device at 0000:01:00.0 into 8x mode
agpgart: Found an AGP 3.0 compliant device at 0000:00:00.0.
agpgart: Putting AGP V3 device at 0000:00:00.0 into 8x mode
agpgart: Putting AGP V3 device at 0000:01:00.0 into 8x mode

00:00.0 Host bridge: Intel Corporation 82875P/E7210 Memory Controller Hub (rev 02)
00:01.0 PCI bridge: Intel Corporation 82875P Processor to AGP Controller (rev 02)
...
01:00.0 VGA compatible controller: nVidia Corporation NV34 [GeForce FX 5200] (rev a1)

BTW, I had to patch the nVidia driver. It just tries up to x4 AGP...

Thanks.
