Just compile support for LVM into kernel. NOT MODULES!!!

Yes modules, NOT KERNEL!
This is why we have kernel modules. It's a fine environment as-is, why
suggest such a thing as a kernel rebuild??

Here is another example of the deficiencies in the rpm install. The
vanilla kernel rpm install maintains a bootable system, so should the
kernel-xen rpm install. Period.
(Knowing what I do now, my time would have been better served suppling
patches to fix the problems, rather than posting the workaround all
these times...)
