Nvidias 43.49

När jag försökte installera de senaste drivarna från nvidia, 43.49, så stod det att den inte hittade nån "precompiled kernel interface" och att den behövde kernel header files för att kompilera. Jag kör slack 9.0 med 2.4.20 som kernel. Frågan är var jag hittar sourcen till kärnan och hur jag ska göra. Har varit inne på slacks ftp, men hittade inget.

Utdrag från logen
" No precompiled kernel interface was found to match your kernel; would you li
ke the installer to attempt to download a kernel interface for your kernel f
rom the NVIDIA ftp site (ftp://download.nvidia.com)? (Answer: Yes)
-> No matching precompiled kernel interface was found on the NVIDIA ftp site;
this means that the installer will need to compile a kernel interface for
your kernel.
ERROR: Unable to find the kernel header files for the currently running kernel.
Please make sure you have installed the kernel header files for your
kernel; on Red Hat Linux systems, for example, be sure you have the
'kernel-source' rpm installed. If you know the correct kernel header
files are installed, you may specify the kernel include path with the
'--kernel-include-path' commandline option.
ERROR: Installation has failed. Please see the file
'/var/log/nvidia-installer.log' for details. You may find suggestions
on fixing installation problems in the README available on the Linux
driver download page at www.nvidia.com. "
