I'm trying to get 2GB to work (and I'm having a problem -- perhaps because I believe Documentation/memory.txt doesn't cover the issues I'm facing). I've not yet bothered with highmem, but I will if building a 64 bit kernel doesn't get me access to 2GB. Does that answer your question? Thanks, -- Raul
