If you link your initramfs into the kernel image, you avoid that problem
entirely: as long as you keep a working kernel around and LVM doesn't
change radically (unlikely to happen), you will always have a working
rescue system, inside the kernel image.

(Personally I use LILO, but /boot is still not in LVM because LILO can
boot from LVM and it can boot from RAID-1, but not both, and I prefer
the RAID-1 peace of mind. Everything else is LVM-on-RAID-5.)
