well, it is heuristic anyways, and it could be improved.

run with fou4s -vv --checkd , to see what I mean, or look at 
getKernelVersion() (line 1044)
and the kernel related code of checkDeleted (line 944)

rpm -qf /boot/vmlinuz gives something ugly, e.g. k_deflt on older boxes
and kernel-smp-2.6.5-7.111 on your box, so the package name sometimes contains
the additional information, but we cannot rely on that.
and the uname -a (resp. /proc/version) does sometimes not contain the
release information, so this is not reliable either.

therefore Markus compares the buildtime of the currently run kernel
 ("Wed Oct 13 15:45:13 UTC 2004" in your case, as listed above)
with the buildtime of the kernel package
  rpm -qf --qf "%{BUILDTIME}" /boot/vmlinuz

[what does this say on your box? ]

and when they are not within one day, it gives you a hint to reboot.
