Don't use lilo, use grub. I'm trying to implement lvm support in grub. The idea 
is that grub should read the first lvm on each pv. This first lv must be only on 
this pv. (and have a special name, eg lv_root, so grub can find it)

The kernel should know about all lvm descriptor and the /etc/lvm* should only be 
used for pvcreate an similar programs.
