I am also trying to update Linux 2.4.26 with the corresponding grsecurity patch. I elected to download the newest Knoppix 3.4 (with Linux 2.4.26) and apply the patch from there. But when I look into the ...usr/src/linux-2.4.26 directory, all I see are "Documentation" and "include" directories? I cant find a Makefile or an image? Any help getting to the place where you are stuck would be greatly appreciated.
