oops! DP may be right you can not have /boot on lvm2, grub does not 
anything about lvm (I am too use to lvm on HP).

However you can have /boot on RAID so you need at least 2 partitions, 
one so that grub can find the kernel with the other (or more) for the 
rest of the file systems.

The /boot partition must be either an ext2 or ext3 filesystem and your 
kernel need to support an initial ram disk (initrd).

Also if you make a custom kernel, later that is, leave the raid software 
as loadable modules else the auto activation of the raid devices at boot 
will not happen.

Sorry about the multi-posts on this, had to search for the doc that I used.
