Why bother partitioning?  I also run a Linux SW RAID1 on the host, as you 
know the drive letters can change when working on a server.

Example: Before I created the array (RAID-6), my disks were /dev/sda,  
/dev/sdb and /dev/sdc (spare), the RAID-6 was /dev/sdd.  After reboot,  
/dev/sdd became /dev/sda and /dev/sd[a-c] became /dev/sd[b-d].

In lilo.conf I had:
raid-extra-boot="/dev/sda,/dev/sdb"

If I ran LILO and forgot to fix the lilo.conf to reflect the new drive  
mappings:
raid-extra-boot="/dev/sdb,/dev/sdc"

I could be at risk of ruining the partition?

Hrm...interesting point. LILO could mess up the superblock in sector 0.

I try to avoid such situations when possible, to be safe.

:)

I don't know how LILO would handle it, but I would try to use
/dev/disk/by-*/* instead of the rather unstable /dev/sd* names.

Just my 0.02 cents.
