First question is where are all the configuration settings? On the memory stick or on the RAID device?
How had you actually set the server up - drive layout etc?
I would guess that if you set up the 2 drives with softraid on SME they should easily be recoverable with any linux distro.
So, tell us exactly how you had this set up and we'll see what we can do to help.
I assume you have a good backup in case of disasters.....
