Everything in /proc is just a window into various kernel data structures.
The pseudo-filesystem you see there doesn't exist on disk.  In your case,
that kcore "file" just allows read-access to the ~1GiB of virtual memory
in your 32-bit kernel's address space.  For my 64-bit kernel:

  -r--------. 1 root root 140737486266368 2011-04-19 22:13:33 /proc/kcore

I can assure you that I don't have ~128 terabytes of disk storage or
physical memory on this system.
