When I was last working on an ACPI update (which I think is what's
currently in illumos and OI) Yuri Pankov was helping me test the code,
and observed a problem on his HP laptop that looked something like
this, if I recall correctly.  He did some further experimenting and
found that he could make his laptop boot without the ACPI errors by
attaching the "EC" device a bit later.

He showed me a possible fix, which I asked him to do some more work
on, but then he ran out of time or something.  Maybe you'd like to
pick up his changes and try them?
