I am looking for a precompiled CentOS 3 kernel with grsec patches, and any other useful security patches. I attempted to do this myself, however I got lost in the grsec setup details. The grsec website wasn't terribly helpful either.

Google didn't come up with compiled, working custom Centos 3 kernels with grsec added.

SMP support would be good to have, as I have a dedicated server with a P4 2.4ghz HT cpu installed (with HT enabled).

On a side note, what other useful (as in security wise) kernel patches are there?
