  Modified files:
    sys/contrib/dev/acpica/Subsystem/Interpreter amfldio.c 
  Log:
  Fix the 'write-with-rule' operations to not do an unneeded read first.
  eg: to write an 8 bit value to an 8 bit register, it was first reading
  the old (8 bit) contents, "merging" the new 8 bits in (ie: complete
  replacement) and then writing the new value out.
  
  This was breaking the SMI call on my VAIO PCG-F690, causing the system
  to hang during boot.
