Maybe a bit of clarification is needed: I didn't intend to listen to
vmlinuz. I actually wanted to inspire someone with more time then me to
purposefully use the lossy compression of mp3 (or ogg for that matter)
to see if the decompressed data would still give a somewhat working
kernel. Think art. Maybe even develop this to a greater project where
the zlib-compression of the kernel gets replaced by the lossy
compression of mp3 or ogg. Then set up a machine to repeatedly boot
these kernels compressed with varying compression rates (and make use
of the hw watchdog to reboot the system). Could be more fun then some
kilos of butter in a corner.

Have a nice day/night,

Arnold
