Thanks for this.

The Silicon Image 3114 controller does have a build option, but,
somewhat bizarrely, the Intel ICH6 controller doesn't---how does one
rebuild a degraded array using this controller?  I might try the above
on the 3114.  (At the moment, it seems to be happily working with ar0
set up by atacontrol with the ICH6 controller.)

I am still interested in opinions on the merits of the BIOS-based
setups with these (presumably cheap) onboard controllers versus
setting up ar0 with atacontrol.  Is there a performance/robustness
difference?  (Maybe I should start a new thread on this.)
