AIUI, it cannot be part of LVM, but you can have a separate RAID array for
/boot and put the rest of the system on LVM
On a similar system (with no spare) I have two RAID arrays, md0 and md1.
md0 accounts for ~900M (yes, way too large for /boot, but just in case
...) and has a single ext3 partition. md1 uses the rest of the available
space and has LVM configured with ext3 partitions for /, /home, /var,
/var/mail, /tmp and swap.
Having /boot configured this way means that, no matter which disk fails
the other will still boot in degraded mode.
