...new dual core pentium D's is about? It's all speculation at this point. But there are _several_ factors. But I'm sure the first time Intel saw AMD's x86-64/PAE52 presentation, the same thing popped into my mind that popped into Intel's mind ... Virtualization - The 48-bit/256TiB limitation of x86-64 "Long Mode" There is a "progammers limit" of 48-bit/256TiB in x86-64 "Long Mode." This limitation is due to how i386/i486-TLB works -- 16-bit segment, 32-bit off-set. If AMD would have choosen to ignore such compatibility, it would have been near...

My current thought is to get an Opteron-based system, but load it (initially, at least) with the 32-bit i386 version of CentOS. That buys me near-term ghc compatibility. In the future,
