I really can comment on that, I only briefly looked at ksymoops, and never looked for altenatives ( didn't need to)

Hello de2zotjes,
            how to use it for conditions like this:-
    I have RH9 with its default kernel 2.4.20-8. i downloaded 2.4.24 kernel and make some changes to it and compile and create image from it. i add entry at GRUB to boot that image.
   Then when i boot it i get oops message. now i want to debug it and know which location or statement cause it? ksymoops require
-k /proc/ksyms (default)
     -l /proc/modules (default)
files but how can i give it as i am unable to boot that new image. i am able to boot nrmal statrup kernel.

The text I brought to your attention addresses this problem as well.
As it says you have 3 choices:
1) hand copy the error codes to a file you feed to ksymoops
2) boot with a serial console and capture the error text on a remote machine
3) patch the kernel with a dump hack

Apart from those general tips you are basically on your own, I don't specialize in oops-tracing...
