This is not the case on at least amd64/i386.

The uncompressed, unstripped vmlinux file at the top of the upstream
linux build tree. For amd64 it is this file in the linux-2.6 build
tree:
edmonds@chase{0}:~/src/linux/linux-2.6$ file linux-2.6-2.6.23/debian/build/build_amd64_none_amd64/vmlinux
linux-2.6-2.6.23/debian/build/build_amd64_none_amd64/vmlinux: ELF 64-bit LSB executable, x86-64, version 1 (SYSV), statically linked, not stripped
> The later is not possible for size constraints.
Why?
edmonds@chase{0}:~/src/linux/linux-2.6$ ls -1sh linux-2.6-2.6.23/debian/build/build_amd64_none_amd64/vmlinux
5.0M linux-2.6-2.6.23/debian/build/build_amd64_none_amd64/vmlinux*
