If building a kernel is as simple as building other programs from source 
(i.e. configure, make, make install), I could do that. I'm using Debian 
at the moment. Presumably I'd need a compiler of some kind, which I 
could obtain from the repos. I am not sure how one would apply patches 
to the kernel, however. Would I be able to compile a modified kernel and 
add this to grub whilst retaining the ability to boot in the unmodified 
kernel?
