Regarding "alt+sysrq+reisub" being a bit awkward: If I remember correctly,
"Alt" must be held down during the entire sequence, but sysrq can be let go
of once hit... or maybe I've got that backwards... but I do remember that
after so long of trying to type "reisub" with my nose, some kind person
finally informed me that I could let the one go. :) It was on one of
these lists...
