With 2 GB in place, the kernel boots just fine, but with 4 GB, it reports:
kernel direct mapping tables upto ffff 8101 5000 000 @ 8000-f000 PANIC: early exception rip ffff ffff 8016 f002 error 0 cr2 4230 PANIC: early exception rip ffff ffff 8011 d1fe error 0 cr2 ffff ffff f5ff d023
and some other lines, which I didn't jot down on paper... These were copied from some Fedora Core development kernel version after 2.6.15-rc1 (last working one) in a box with 4 GB memory.
Those hex values didn't have intermediate spaces in them, though. That was me trying to understand 64 bit values.
Last working kernel with all 4 GB memory in the box was 2.6.15-rc1 Since then the kernels have failed to boot at all, unless machine PHYSICAL memory is stripped down to 2 GB. Command-line options (e.g. "mem=2G") don't help at all.
