So I returned the script to its original state, and the same problem
is still there, running up-to-date etch. I put in set -x as you
requested, and it looks like MD_MODULES gets set twice. Initially, its
set appropriately as "linear ..." but later it just get set to "0 1 5"
which of course causes the modprobe to fail. 

Unfortunately, it won't boot in this scenario (maybe... I'll try
init=/bin/bash) so I've got to rig up a serial console to capture the
messages. 

I'll report back with more.
