you mean, vmlinuz right? the bzImage right? not the vmlinux....
because that's the one GRUB handles...not vmlinux one...

well, in that case, see this first:
$ file -k -z  /boot/vmlinuz-2.6.32-31-generic

/boot/vmlinuz-2.6.32-31-generic: Linux kernel x86 boot executable
bzImage, version 2.6.32-31-generic (buildd at rothe, RO-rootFS, root_dev
0x801, swap_dev 0x3, Normal VGA\012- x86 boot sector, code offset 0x5

i am sure you will get idea based upon the above file identification,
on what vmlinuz is and how is it supposed to be treated by boot
loader....
