Software:
- 2.6.15-mm1
- kexec-tools-1.101 + kexec-tools-1.101-kdump.patch

Test-Procedure:
- Built first kernel with CONFIG_KEXEC enabled.
- Booted into first kernel with command line options crashkernel=64M@16M.
- Built second kernel for 16M physical start location with CONFIG_CRASH_DUMP, and 
  CONFIG_PROC_VMCORE enabled.
- Loaded second kernel with following kexec command.

  kexec -p vmlinux-16M --args-linux --crash-dump --append="root=<root-dev>
  init 1 maxcpus=1"
- Invoked kdump using sysrq-c and second kernel is booted.
- Got the dump in /proc/vmcore and copied the /proc/vmcore to disk.
- Booted back to first kernel and ran gdb on stored dump image.
