I usually create the boot and swap partitions as RAID1 also.  Swap so 
running processes won't crash if 1 disk fails and boot so the copy stays 
up to date as kernel updates are installed.  But if you start with a 
copy of your working /boot you should be able to fix it up with a 
rescue-mode boot from the install CD when you need it.
