It does :)  If you did "raidctl -A yes raid0" then the raid set will 
be automatically configured on boot.  Just boot a GENERIC kernel
(or something that has RAIDframe in it) and then use "raidctl -G raid0" to 
generate the appropriate config file.

It would eat data if you got the size wrong and say tried to do stuff
with files on the filesystem.  If the autoconfig doesn't work (it 
should) contact me directly and we'll look at some other options...
