We don't, here are some test results after fixing above:

first, full display after installing new adm9240:

peetoo:0-002d$ ww_adm9240

Turn up full speed (it has a variable resistor in series with 
thermisor to calibrate operating point)

Fan clock divider adjusted down one:
 fan       rpm     min    div   alarm
  1       4018       0     4      --
  2          0       0     8      --

Hysteresis, fan clock divider stays at 4:
 fan       rpm     min    div   alarm
  1       1474       0     4      --
  2          0       0     8      --

Fan clock adjusted downwards (stuck my finger into the fan :o)
 fan       rpm     min    div   alarm
  1        861       0     8      --
  2          0       0     8      --

 fan       rpm     min    div   alarm
  1          0       0     8      --
  2          0       0     8      --

All fixed?

Cheers,
