You need to patch the Nvidia kernel driver to handle changes made in the 
2.4 tree. You can either:

1> Get on irc (Server: irc.openprojects.net, Channel #nvidia) and request 
the patch from there. (You need to be able to do DCC transfers for this to 
work). There is patches for 2.4.0-test1[0-3] and for 
2.4.0-[prerelease/final], so get what you need that way. The bot to request 
from is usually iCE-DCC, and you can request a list using '/msg iCE-DCC 
xdcc list' and request a file using eg: '/msg iCE-DCC xdcc send #10' (if 
you wanted file 10 that is).

2> Alternatively, if you e-mail me, I could probably forward you the patch 
or, if people don't mind too much, I could post it to the list (I'll wait 
for comments on this first!).

The patch is about 1k for test10, and about 3k for prerelease/final. 
Remember, this patches Nvidia's driver shim source code, and not the 
kernel. You could unpack the .src.rpm and add the patch to the compile 
process if you were really game, but I did it from the .tar.gz and it works 
fine for me. YMMV of course.

BTW: Common problem is that people complain that the make still gets 
includes wrong. Make sure you compile the kernel and it's modules 
completely. I compiled the kernel and modules, rebooted into the new 
kernel, and then compiled the Nvidia driver. The last step of Nvidia's make 
process (for the .tar.gz) is to actually insmod the driver to make sure it 
worked, which will probably fail on any other version of the kernel.

Of note: Nvidia have a new driver in the works, that should be much nicer 
re: kernel interface.
