That is, that you can find them in an uncompressed form. If you fees adventurous you can probably coax the compressed data somehow through the bootloader decompressor, or the xz or deflate implementation found in the Linux kernel. Unfortunately these days modules tend to be compressed as well, but it should be possible to convice libdl to open a .ko file. If not you can always mmap it PROT_READ|PROT_EXEC and follow the symbols entries through the TLD yourself.
