Why spend time re-inventing the wheel? Most distros already support a "crash kernel" for specifically this purpose. (It basically uses kexec to boot into the alternate kernel, which does the dump and then re-reboots into whatever your standard kernel is. This is in general a lot safer than trying to trust your crashing kernel to do a dump cleanly.
