from where to get vmlinux for rhel4 u2

[lnx lrn]

Hi,

I need vmlinux file so that I can profile the kernel.
as per the link
http://people.redhat.com/anderson/crash_whitepaper/invocation.html
vmlinux comes in kernel-debuginfo package
but on rhn shows this package only for 2.4 kernels

from where I can get vmlinux for rhel4 u2
one option is to build the sources, any other option ?

-lnx
