Actually, the boot program does not know how to decompress the kernel.
A compressed kernel is loaded as data in another program that is
loaded by the boot program. This other program then decompresses
the kernel into the proper place in memory and then jumps to it.

I don't think it is possible for a completely MI implementation, but
I'm sure the decompression routines could be MI.
