What I don't get is that on this page, patches never apply to a released
version of the kernel, but always to a rcX development one. The one I
tried, for kernel 2.6.26 and 2.6.30 both fail to patch (there's some
rejects on the Makefile). Why isn't the author publishing something that
people can actually USE ???
