That patch only makes lilo map LVMs to an appropriate physical device.
It does not guarantee that you will be able to boot off of an LV on a
physical volume. As such, the behaviour is still undefined.

Consider a situation where /boot spans multiple PVs, and you will see
lilo fail to boot the system correctly.

If /boot happens to be on a single PV, then it will work, but it is
still not guaranteed.
