Many thanks for the positive replies, the suggestions to cvsup to today were
spot-on: the ata modules now load fine from loader.conf on the MP machine. 

To answer the troll: it's fast, free, proven, and they were $50 on eBay.

Not sure on either of the above specifically, but quite a bit of work has
gone into IRQ routing and the ata subsystem since 6.0R.  Your problem sounds
somewhat similar to what I was seeing on a Dell 4way box back in August
which was fixed in Sept

regardless, there are a lot of bugfixes since 6.0

To today is quite stable.  The FreeBSD folks are preparing for a release
right now and what is in the tree works very  well.
