I've placed copies of the dmesg.boot from each of RELENG_6, RELENG_7,
and HEAD in www.catwhisker.org:~david/public_html/FreeBSD, as well
as copies of the kernel configs (joining the ASL/DSDT stuff). I
just added output from "sysctl hw.acpi" from each, as well:

Errr... hmmm? The machine shows "BIOS Version: A11".
> . might you have any BIOS settings re performance/economy/cooling set?
My settings under "Power Management" (in the BIOS config/setup menus):
BATTERY AC
_______ __
Brightness: [XXXXX ] [XXXXXXX ]
Power Management: Enabled Enabled
Display Time-Out: 4 Minutes Disabled
Disk Time-Out: 3 Minutes Disabled
Suspend Time-Out: Disabled Disabled
22D Time-Out: Disabled Disabled
Smart CPU Mode: Enabled Enabled
Display Close: Active Active=20
Ring/Event Resume: Enabled
Alarm Resume: Enabled
Wakeup On LAN: Disabled
Intel SpeedStep(tm): Enabled
CPU on AC: Automatic
CPU on Battery: Automatic
Auto On Mode: Disabled
Auto On Time: 00:00
Most of the above are defaults; I disabled Suspend & S2D on battery,
as well as told it to remain active on battery if I shut the lid.
Everything else should be a default setting.

I am not running it in a docking station or port replicator.

I did not see how to get the CPU heat sink off, so I didn't mess with
that.
I did remove the keyboard, and it appears that the keyboard acts as a
secondary heat sink for the video card; I did clean both surfaces (the
chip & the underside of the keyboard) and place a thin layer of thermal
compound on the chip before re-seating the keyboard. That does not
appear to have had a noticable effect either way.
Thanks for the help so far.
I'm getting the distinct impression that it's likely that some of the
hardware is failing, and that I either need to have the machine repaired
by someone competent to do so (as opposed to me) or I need to consider
replacing it. (There are, after all, significant parts of the machine
that are over 5 years old. And I've been tracking various FreeBSD
branches on it just about daily as long as I've had it and it's been
working.)
Peace,
david
