The kernel was compiled with kernel symbols (genksyms) but your modules were compiled without genksyms. Fundamental mismatch, no way they will load.
At some stage you have compiled the normal modules correctly, do "nm -A /lib/modules/2.2.13/*/*.o" and look at the symbols. A lot will have the _Rxxxxxxxx suffix, this matches the kernel so you can load them. But your ide modules do not have the suffix on the symbols so they cannot load.
Unless you can work out what you changed to get this mixture and can correct the problem, the safest option is save your .config, make mrproper, restore your .config and rebuild the kernel and all modules from scratch, then reinstall. It could be something as simple as genksyms not working with the new compiler and/or library but rather than stuff about trying to locate the problem, clean out and restart.
