Have you tried using the Alt+Sysrq+c key combination ?
We had checked in some changes to enable non-disruptive dumps to be taken this way as well (i.e. you can get a dump without having to reboot the system) but that piece is going to be in lkcd 4.01.
BTW, you can also trigger a crash dump conditionally using dprobes.
