Yeah you are right, on 64-bit platforms that could have happened. I actually thought that CONTIGUOUS_BUFFERS took care of 4GB, but on checking it does not.
So clustering should have been disabled then (which in the in-kernel drive it is not). Now both 2.4 and 2.6 make that guarentee. The only argument for disabling clustering would be for 2.4 for CPU cycle reasons.
