Several suggestions, please use the vanilla 5336 drivr from nvidia.com, 
not a patched release. The 5336 driver support 2.6 out of the box so no 
patching is necessary.

Just try this, please disable ACPI. When ACPI is enabled I have a 
astonishing frame drop of 10% or greater, so please edit your lilo.conf 
and pass the acpi=off option to the kernel.

I have the identical setup as you, and I am having no problems at all.
My setup is
1. Vanilla kernel 2.6.2 compiled with athlon optimisations, preemption 
enabled, acpi turned off at boot. I am using NVIDIA's agp driver.

cat /proc/driver/nvidia/agp/status
Status:          Enabled
Driver:          NVIDIA
AGP Rate:        8x
Fast Writes:     Enabled
SBA:             Enabled

Hmm.the NVIDIAxxxx.5336.run package from nvidia.com supports 2.4 series 
without any problem. ALso I have noted that surprisingly the 2.4 series 
kernels give better frame rates for Neverwinter nights and other 3d games.
 
However you can try disabling acpi, thats the cause of most problems in   
the nforce2 motherboards.
