This was only for the sil0680 chipset. HPT372 e.g. is completley unsupported 
in -stable.
I've never tried ataraid with "non-raid" controllers but I doubt that 
detach/attach would work. I asked Søren about the missing addspare in -stable 
but never got any answer.

I just had extreme problems with ataraid on -current and am awaiting some 
response about these issues, I just can hope that some time ataraid will be 
lifted to what the man page promises.
