Hard, real hard, lilo uses only bios calls, and in 512bytes
you just cannot fit anithing better, all other os that use lvm
have a /stand partition at the beginning of the disk,
it can be mirrored but it must necessarily be contiguous

i personally love modular kernels, so i'd use initrd anyway, but
i agree vgchange -a y could be handled by the kernel.

but i also believe that this would be easier to debug/mantain in
user space.
