If we don't mix page sizes, but just increase the default from 4k, does this still add a lot of complexity in your eyes? I can't see why it would ... ?

I believe one of the traditional problems stated for this case is the amount of virtual address space taken up by all the struct pages for a machine with large amounts of memory (32-64Gb). At the moment, the obvious choice of architecture is still 32 bit, but maybe AMD Hammer will fix this ... Unless someone has a plan to move all those up into highmem as well ....
