My spare X61T may be dying... :(

Symptoms:
1. Indicator LEDs except Wifi and Bluetooth don't work anymore. Power button on the LCD still works, not sure about the Tablet-related buttons.
2. The thinkpad-acpi kernel module (I'm running Debian Testing) reports that access to the EC (embedded controller) is misbehaving, and falls back to ACPI TMPx access mode.
3. As a result of #2, I've lost thinkpad-specific sensor readings, including fan speed. Coretemp and standard ACPI-based temp sensors appear to be working.
4. The fan doesn't appear to be spinning even when the temps are high. since this is a low-voltage processor, it's not that critical...
5. Some device wants some I/O addresses already claimed by the LPC bridge (part of the ICH southbridge) The message before the error on dmesg mentions the SMBUS controller.
The laptop remains usable though-- I'm actually typing this post on this machine.
I'll try to investigate deeper, but since it's just a spare/extra machine, it might be better to simply dismantle it and use the remaining parts.
