is turned off by default and could be enabled by defining LOADER_BZIP2_SUPPORT make variable. Also make gzip support optional (turned on by default) - it could be turned off via LOADER_NO_GZIP_SUPPORT make variable. Please note, that due to limit on the amount of memory available to the loader(8), it is possible to load modules/kernels compressed with the smallest block size supported by the bzip2 - 100k (`-1' bzip2(1) option), however even in this mode bzip2(1) usually provides better compression ratio than gzip(1) in its best compression mode.
