Comment(by pgf):

 collateral info:
 {{{
 <Mitch_Bradley> pgf: do you have a heat spreader?
 <pgf> Mitch_Bradley: no.
 <Mitch_Bradley> okay, that is useful to know
 <pgf> Mitch_Bradley: i also have the latest DCON irq ECO applied.
 <pgf> http://wiki.laptop.org/go/XO1.5_DCONIRQ_ECO#Alternate_ECO
 <Mitch_Bradley> pgf: OFW does power-saving things only at the ok prompt,
 so the hotness suggests that it isn't sitting at the ok prompt behind a
 frozen screen
 <Mitch_Bradley> I wonder if it is stuck waiting for some status bit to
 flip
 <pgf> right -- e.g., if it's waiting for SMBALRT to do something, it
 probably won't happen.
 <Mitch_Bradley> so dconirq is no longer connected to smbalrt#, but rather
 to GPIO12
 <pgf> Mitch_Bradley: right.
