if you have a "modern" linux distribution, I would direct you to have a 
look at udev. You can write identification rules which assign static 
labels in /dev to your devices based on serial id's, etc.
But beware, writing udev rules requires a virgin and at least two dead 
chickens, so I would either start using some device-independant layer 
like lvm / fs labels or forget about this issue.
