If you're wanting to do pure concatentation of different-sized disks, 
then you'll have to use ccd, since RAIDframe doesn't handle that... 
If the disks are all the same, then using a RAID 0 w/ RAIDframe should work 
just fine..

Somewhat known :)  But it wouldn't hurt to file a PR anyway... (Is the panic 
RAIDframe-related, or something else? )

Remember to do both 'raidctl -I' and 'raidctl -i' too... then, copy rfconfig 
to /etc/raid0.conf , and /etc/rc should use /etc/raid0.conf to automatically 
configure the RAID set at boot... (I *think* the right stuff to do this
is in /etc/rc for 1.4.1, but I don't remember any more... :-/  If it isn't
you can certainly borrow those parts from 1.4.2.)
