I thought that was the optimum configuration.  (I have ServerWorks in 
my Dell 600SC.)
My understanding of the problem with the ServerWorks chipset was the 
inability to recognize slave drives; I still have this problem but have 
just put the server together so have not worked on it much yet.

What were your atacontrol settings, and how did you differentiate the 
results (dmesg, sysctl)?
FWIW, my drive recognition problem exists in 5.0 and 4.7-Stable.

I'll forward separately to you a message I received a couple of weeks 
ago on this or a related issue.
