Can I use a stock kernel.org kernel anyway ? >A. Yes. But you obviously lose all the 'add ons'. The key one being NPTL support. Dropping in a kernel which does not support NPTL can cause all kinds of headaches. I ran in this mode for a short while for various reasons. Mozilla, OpenOffice, and WINE consistently wedged. Presumably this happened because the Fedora versions actually relied upon Posix compliant things like thread signal delivery and if you drop in an old kernel you get the old non-compliant signal delivery behavior.
