>Description:
	Where envstat used to report sane values for all my systems
	fans:

  CPU Temperature:     55.500 degC
   MB Temperature:     31.000 degC
    Vcore Voltage:      1.240 V
     +3.3 Voltage:      3.296 V
       +5 Voltage:      5.120 V
      +12 Voltage:     12.460 V
    CPU FAN Speed:       1022 RPM
CHASSIS FAN Speed:       1713 RPM
  POWER FAN Speed:       1117 RPM

	it does no longer display the last 2 fan speeds correctly
	but instead prints 2^32 - 1. Every time envstat runs, it
	causes the kernel to print:

ACPI Error (dswstate-0329): No result objects! State=0xc2fbd000 [20060217]

	Note in the above fragments of dmesg that approximately
	the same messages are printed when attaching aiboost and
	apm.

>How-To-Repeat:
	Run envstat on a system with similar hardware as mine.
>Fix:
	I have no idea. Let me now if I should provide more input
	like dumps of acpi tables or such.
