 As requested, here is a copy of my ASL:
 http://www.nbritton.org/uploads/compaq/armada_17xx.asl
 
 This bug also affects the whole Armada 1700 series.
 
 The work around I submitted does NOT work if the system is below the 
 hw.acpi.thermal.tz0._ACx threshold, if it is below this threshold at 
 system boot the fan will NEVER turn on even if 
 hw.acpi.thermal.tz0.active=1 is set in loader.conf.
 
 Also is it possible to just extract the AML code from the Linux patch an 
 use it to make a FreeBSD patch? I don't know as I'm not a programmer and 
 I'm not sure of any GPL issues.
