I find it hard to believe that redhat would ship an unpatched kernel. IMO :)

you can check it with rpm -q kernel-headers or something like that.

You are right that it is puzzling the first few time you do it and there
are people on this list who swear it has become obsolete due to rpms,
but I have found that installing the kernel is a very straight forward
process once you understand how and extremely handy to know how to do.
The lowlatency howto has a good explanation of what to do and in the
process you can learn about installing the low latency patch
You can find the most up to date version as part of the LAU-guide (see
below). I use it myself occasionally as a reference and it has beeen
thoroughly tested as a guide.
