It would be useful if anaconda displayed a info box telling people when
they were considering installing 32b Linux on systems with 32/64b CPUs
and more than about 800MB of RAM. 
In disk and networking the win from 64b is considerable due to much
reduced low memory fragmentation and in general there's a lot less
stuffing about with DMA. It is well worthwhile for people to install
64b Linux when that is reasonable, but as this thread has pointed out
determining 64b capabilities prior to installation is a big ask of
people unfamiliar with the intricacies of their CPU vendor's products.
Thus the requirement to let installers of 32b Linux know when a better
choice is available (but of course, not to insist upon that better
choice -- the info box should only be informational).
 More technically, when /proc/meminfo's LowTotal < MemTotal.
