I tried enabling all the options in the Linux kernel (make allyesconfig) and compiling it (make all)
Here is the result of the size's of the kenrel tree
Size of the kernel downloaded (tar.bz2): 44 MB
Size of Uncompiled (clean) kernel tree: 294 MB
Size of the compiled kernel tree: 4.5 GB
Size of vmlinux generated: 442 MB
Size of the bzImage: 16 MB
I ended up clearing most of the unwanted things in my home directory trying to make space for the compilation :-)
