a bzImage, whether it is compressed using bzip2, lzma, whatever remains a 
bzImage and as such can be used without knowing the compression used.

The "Function not implemented" error appears when the kernel you are running 
this command does not support the kexec system call, recompile with support 
for it and you should be fine.
