Wrong, ataraid works fine on 5.x.

However there are some ATA software RAID setups that I havn't done the 
metadata code for yet, but they'll get there eventually time permitting. 
You can always use atacontrol to setup a RAID on *any* ATA 
disk/controller setup, however you will need a BIOS with a known 
metadata layout (Promise/Highpoint) to be able to boot from it (se man 
atacontrol(1) for details)..
