You have to do that anyway.  If a device has managed to DMA all over
the kernel text, you have to have a completely independent dump
mechanism.  I personally HATE the idea of a kernel dump driver and
think that MPE's solution (on a TOC, dump the ram after reset) was
more elegant and easy to prove correct.

Note that grant disagrees with me on this.
