The boot process on a WRT54GL works the following way: 1. CFE gets loaded by the boot rom from flash 2. CFE loads the loader from the flash and gzip uncompresses it 3. CFE starts the loader 4. The loader stores the FW arguments and relocates itself to BZ_TEXT_START (now 0x80600000) 5. The loader reads the Linux image from flash 6. The loader lzma decompresses the Linux image to LOADADDR (0x80001000) 7. The loader executes the uncompress Linux image at LOADADDR The BZ_TEXT_START was set to 0x80400000 before. When the kernel gets uncompressed and is bigger than BZ_TEXT_START - LOADADDR it overwrote the loader which was currently uncompressing it and made the board crash. Increase the BZ_TEXT_START my 2 MB to have more space for the kernel. Even on 16MB RAM devices the memory goes till 0x80FFFFFF so this should not be a problem.
