sgolds, maybe its unnesessary to limit memory to 4 Gb for budget platforms. First, I suspect socket 734 supports no more than 3 Dimms. There is no 2 Gb Dimms yeat, afaik.
Second, socket 734 single-channel controller has visible performance degradation when you add memory (though not as bad as P4).

So, when you have good performance only with 1-2 Gig of ram, what's the point to disable 64 bits anyway?
