OK, easiest things first, could you show us:
1. the output of "grep -i highmem " toward your running kernel config file?
2. the complete entry grub/lilo stanza that is responsible to execute
your current running kernel
I need to see whether you're really enabling highmem support and
whether you use kinda kdump etc that might reserve some space in
RAM....
