Right. If Opteron really takes off, and becomes supply constrained, IBM would be a great source. To me, there are many factors besides capacity that would drive demand.
One of those many factors, and a very important one, would be IBM as a second source for the processors. This would insure OEMs that there will be a steady supply and make the whole solution an easier sell to corporations.
Yes, this is a 'what if' scenerio. Paradoxically, AMD may not be able to exceed Dresden capacity on their own, but could sell out Dresden plus a bunch from IBM with such an arrangement.
