As more information regarding this, if you do as Nathaniel says above and use the latest kexec-tools package with the "1...@16m" syntax, you can get past the "Command line overflow" problem and load the crash kernel, but you may find that when invoking the crash kernel you get a kernel OOPs in machine_kexec, arch/x86/kernel/machine_kexec_32.c due to a NULL pointer dereference. To avoid that you need the patch described in this bug here: http://bugzilla.kernel.org/show_bug.cgi?id=13265
