I'm open to doing this for RELENG_5 but not -current.  I'll contact re at . 
  I'll also work on adding a quirks option to disable the timer for 
-current.

Yes, I agree.  However, we do need to maintain this and my goal all 
along has been to add more quirks (hence the name "acpi_quirks", not 
"ACPI blacklist.")

Note that Linux doesn't have this problem since they outright disable 
and refuse to support ACPI on all systems older than 2001 (we block BIOS 
older than 1999.)  Most of the BIOS in our quirks table are from the 
period 1999-2001.
