Ingo Molnar's kernels can one download from here:
http://www.kernel.org/pub/linux/kernel/projects/rt/
If I shall have downloaded from here the linux-2.6.24.7.tar.bz2
kernel, then must I patch it from here:
http://www.kernel.org/pub/linux/kernel/projects/rt/ ?
Or maybe it's better for me to just install from Debian Backport the
linux-image-2.6.25-2-686 kernel?
