hmmm.  okay.  i guess i need to find acpi docs, then.  so, i take
it that you're saying that the BIOS doesn't do anything independently
after initial boot?  i guess that's how i've always assumed things
were, but lately i've been seeing reference to comments like "the bios
does this", or "the bios does that", as if it were managing some h/w
aspects without kernel intervention.

is there a log, or a way to turn on logging, for _all_ acpi/bios events
as they're reported up to the kernel?  (okay, i guess i'm starting
to ask non-thinkpad-specific questions... :-)
