This is a quick 'howto' recompile a grsecurity patched kernel for Ubuntu servers (at the time of this writings the latest Ubuntu LTS is 10.04.2). This guide, with some modifications, might work (or fail miserably) for the latest kernels. But since I am running servers (web, mail, dns) I do not need any fancy kernel support for the latest video/audio features. I won't discuss any grsecurity or kernel configuration options here. I assume you know what you're doing.
