What are the advantages of this over running the Fedora kernel?

There are probably no real advantages running a custom kernel over the Fedora kernel for most users. Here's a list of my imaginary advantages.

[1] I see some (small) memory savings - approx 5 mb, this box is old and slow and needs all the help it can get.

[2] I don't load a lot of modules for things that my hardware doesn't have (or I don't use). Less software loaded means less bugs.

[3] The kernel is the most important piece of software on your box, do you really trust Dave Jones hacking after he's downed 3 pints (just kidding DAVE!)

[4] I enjoy following the kernel developers mailing list (I need to get a real life).

Regards,

John
