Hm, I think that's rather big....here after compilation (of course, my
.config is likely different than yours), 2.6.36 takes approximately
1.7 GiB

Together with the object files during linking stage, I believe :)

Yup...

AFAIK, /lib/modules/<version>/build is symlink-ed to that source code
dir, so IMHO don't delete it..

I think the best way here is to do "make clean" and then followed by
"make modules_prepare". That way, your kernel source dir is build with
files enough to compile external modules whenever needed, but not too
bloated
