I have need to support and help people sell machines that use 32GB of
directly addressable memory. In fact, the EM64T cheat will shortly
become an embarrasment to Intel when people find out that EM64T with PAE
is *not* the same as Opteron (36 vs. 40).
I'm afraid I don't understand the 'unreasonable' argument here. Linux is
eating your lunch today. Do you want it to eat your dessert as well?
