You can work around this problem with info from PR kern/89879

http://people.freebsd.org/~ariff/acer_ferrari/

A future acpica import may address this problem.  The aml is accessing a 
field before it's defined.  The newest acpica adds support for lazy 
evaluation (even though this is out of spec).
