By definition, if the system is truly hung, then there's way to give
control to the part of the kernel that takes crash dumps.

If this system is only pseudo-hung, you can escape to the debugger and
tell it to `call boot(0x104)' and it will attempt to take a crash
dump.  Often times, the problems that cause a hang are the same ones
that may cause a crash dump to fail.
