Kernel Compression Mode

The old and tried gzip compression. Its compression ratio is
the poorest among the 3 choices; however its speed (both
compression and decompression) is the fastest.
Its compression ratio and speed is intermediate.
Decompression speed is slowest among the three. The kernel
size is about 10% smaller with bzip2, in comparison to gzip.
Bzip2 uses a large amount of memory. For modern kernels you
will need at least 8MB RAM or more for booting.
The most recent compression algorithm.
Its ratio is best, decompression speed is between the other
two. Compression is slowest. The kernel size is about 33%
smaller with LZMA in comparison to gzip.
