The solution

Add all charset-modules to the kernel, recompile & install. I were using: Linux Kernel v2.6.13.2

You'll find the modules which were not compiled as modules in: File System - Native Language Support

...

I've added all modules but adding Codepage 437 (United States, Canada) would also work.
