Scott.
Think the OP is talking about applications where the crashed kernel is dead and
gone but some embedded hardware support still permits an external debugger
(serial, JTAG or similar I guess?) to read out the content of physical memory.
The result of that is a file that's the equivalent of a dd image of /dev/mem
although it's not taken from the live system by reading /dev/mem from userspace.
