Bug#591836: linux-image-xen-686: Please add support to PAE

Hi Ben,

Thanks a lot for your reply. The bigmem kernel worked fine.

I don't know.  Are you able to access more than 3 GB with
linux-image-2.6.32-5-686-bigmem, or with any other Linux version?

Also, please send the output of the command:
  grep -r . /sys/firmware/memmap/

Ben.
