Default 3D working but slow: AGP-Status disabled

I have two machines, one Duron 1600 with a Geforce 4 MX and another one with an AMD64 2GHz and a Geforce 6200, both Kubuntu Edgy and 1.0.9629.

The machine with the GF4 shows about 1300 fps with glxgears, the GF6 only 1100. That can't be right, right?

I noticed that AGP seems to be disabled on the GF6 machine:
# cat /proc/driver/nvidia/agp/status
Status:          Disabled

AGP initialization failed, please check the ouput
of the 'dmesg' command and/or your system log file
for additional information on this problem.
But it should be possible to enable it:
# cat /proc/driver/nvidia/agp/card
Fast Writes:     Supported
SBA:             Supported
AGP Rates:       8x 4x
Registers:       0xff000e1b:0x00000000
The GF4 machine shows this:
# cat /proc/driver/nvidia/agp/status
Status:          Enabled
Driver:          AGPGART
AGP Rate:        8x
Fast Writes:     Disabled
SBA:             Enabled
# dmesg | grep -i agp
[17179590.820000] Linux agpgart interface v0.101 (c) Dave Jones
[17179590.832000] agpgart: Detected VIA KT400/KT400A/KT600 chipset
[17179590.840000] agpgart: AGP aperture is 64M @ 0xf8000000
[17179612.660000] agpgart: Found an AGP 3.5 compliant device at 0000:00:00.0.
[17179612.660000] agpgart: Putting AGP V3 device at 0000:00:00.0 into 8x mode
[17179612.660000] agpgart: Putting AGP V3 device at 0000:01:00.0 into 8x mode
I think that my chipset is not recognized on the GF6 machine:
# dmesg | grep -i agp
[17179587.496000] Linux agpgart interface v0.101 (c) Dave Jones
Otherwise it should say something like: "agpgart: Detected VIA KT800 chipset", right?

I know that glxgears is not a proper benchmark, but the GF4 machine feels faster than the GF6 one playing UT2004.

Can anyone help me on this?
