As soon as I finish writing raw write disk routines (not using kiobufs),
we can _maybe_ get LKCD accepted one of these days, especially now that we
don't have to build 'lcrash' against a kernel revision.  I'm in the
middle of putting together raw IDE functions now -- see LKCD mailing
list for details if you're curious.

IMHO, GKHI is a good thing -- it would be great to see this used for
ASSERT() cases (something you can turn on by 'insmod assert.o', which
would then trigger assert conditionals throughout the kernel ...) I
realize it would mean some bloat, and I doubt Linus would accept it,
but it's a nifty concept for enterprise Linux servers (especially
those that want quick answers to system crashes).
