This is the right procedure to try. But I have tried a desperate 
approach that worked for me in the past. If the above procedure 
fails, you could try to read the docs on insmod. It has a "force" 
flag, that makes it possible to force the loading of modules not 
specifically compiled for your kernel. Since your kernel version is 
close to the one the mol module was compiled for (2.4.18-0.8a vs 
2.4.18), it stands a big chance to work.

All you have to do is to manually insmod the mol module before 
running startmol. I don't have the details here (I'm running native 
Mac OS right now), but if you don't have the knowledge to figure them 
out, then this procedure is too dangerous for you to try. A full 
backup is never a bad idea, anyway.

Be warned: while it might actually work for you, there's no 
guarantee, and there is even a possibility that this procedure 
introduces instability or system crashes (kernel panic), freezing 
both linux and mol sides. The best scenario is everything working 
just fine, the worst is you losing all of your files.
