What distributions?
On my Fedora 12 laptop:
$ file /boot/vmlinuz-2.6.32.23-170.fc12.x86_64
/boot/vmlinuz-2.6.32.23-170.fc12.x86_64: Linux kernel x86 boot executable bzImage, version 2.6.32.23-170.fc12.x86_64 (mock, RO-rootFS, root_dev 0x902, swap_dev 0x3, Normal VGA
On my debian box:
$ file /boot/vmlinuz-2.6.32-trunk-amd64
/boot/vmlinuz-2.6.32-trunk-amd64: Linux kernel x86 boot executable bzImage, version 2.6.32-trunk-amd64 (unknown@Deb, RO-rootFS, swap_dev 0x2, Normal VGA

This seems to match my two boxes.

What distro is it?

When I build my own kernel on Debian I have:
$ file /boot/vmlinuz-2.6.37.1+
/boot/vmlinuz-2.6.37.1+: Linux kernel x86 boot executable bzImage, version 2.6.37.1+ (rostedt@gandalf) #23, RO-rootFS, root_dev 0x900, swap_dev 0x2, Normal VGA
Your second file looks more like a vmlinux than a vmlinuz file.
$ file vmlinux
vmlinux: ELF 64-bit LSB executable, x86-64, version 1 (SYSV), statically linked, not stripped
