To get a stock stat drive by hand I had to list about 5 kernel modules in the right magic order in /etc/kdump.conf
Neither mount by label or mount by uuid when specified in /etc/kdump.conf I had to hack mkdumprd to get an initrd that even finds the proper disk to mount.
Short version it takes a huge amount of expertise to get what ships with fedora to pass the trivial alt-sysrq-c test. It would probably be about as easy to write you own custom initrd by hand.
