Juliano: They might not be the same driver (e.g. the NVIDIA driver being used in 2.6.15 is older than the one you are using with 2.6.20) or your hardware is being driven in a fashion that the NVIDIA driver no longer agrees with in a new kernel (e.g. the new kernel is detecting your hardware in a different fashion causing two devices to conflict...). It's hard to say without detailed information though. Sometimes you can glean clues as to what the issue is by looking in /var/log/Xorg.0.log and the output of running dmesg . We would really need to see the output of those things after things become slow to stand any chance of solving the problem...
