this looks great.  thanks again for taking this on.  i haven't yet had
a chance to do a close review (will do tom'w), but assuming the
details are right, just a couple of initial comments...

like chris, i don't think this is a great name.  we already use at
least two naming styles (olpc_dcon_xo_1_5.c, olpc-pm-1.5.c) and
introducing a third doesn't seem great.  frankly, i think "xo15",
"xo175", etc, would be sufficient, since the lack of a decimal is
unlikely to lead to ambiguity, but barring that, i'd stick with using '_'.
(of course, if dcon hasn't gone upstream yet (i don't recall), then
now would be the time to change it too, if we want to change.)

whether or not we eventually decide to apply your DSDT patch, i think
we'll probably want to leave the in-kernel bit twiddling in place for
at least until the new firmware is available.  and i guess i'm
assuming that we wouldn't do new firmware just for this, but would
wait until some more compelling reason came along.
