 The panic should be hopefully fixed(?).
 
 There are two instances of acpivga(4) on this system, but it appears that
 the second one is not supported properly by the vendor:

 If you post the acpidump(8) output of this system,
 
        # acpidump -dt > foo.asl
 
 we have the necessary information to decide whether this is a firmware bug.
