you can use any standard (vanilla) 2.4.x kernel if you
mv /lib/tls /lib/tls-dontuse

(which won't survive one of the rare glibc updates)
and make sure to use the --force-tls=classic option of the NVIDIA installer (in 
case you use it at all).

Why use a standard kernel? One reason could be you want to convert your machines 
into a load-balancing cluster (see http://www.mosix.org), or you need special 
patches (like the PM_TIMER patch together with amd76_pm).
