Kids: do not shove random modules into your kernel. Just because Linus does something doesn't make it a good idea. modversions tries to be clever, but don't count on it; you want module signing for this (where did those patches go?) BTW, I'm fascinated and a little nausiated that you ignore initrds. We've moved half the kernel brains to userspace with udev, initrd and modules; it's really unfair that you're not sharing all that why-won't-my-machine-boot love. Cheers, Rusty.
