[lm-sensors] want memory temperature(i5k_amb), but it doesn't display and sensors-detect can't find all the sensors

Hi, I have a Xserve server with 64bit 10.04 ubuntu and Mac os X server.

I want to know the temperature of memory module (FB-DIMM) under ubuntu, so I
use 'sensors-detect' with following modules find:

Intel Core family thermal sensor...                         Success!
    (driver `coretemp')
Intel AMB FB-DIMM thermal sensor...                         Success!
    (driver `i5k_amb')

then I 'modprobe' coretemp and i5k_amb, but when I use 'sensors', I can only
get cpu temperature, and no memory temperature:

root at lake:/home/szhang# sensors
coretemp-isa-0000
Adapter: ISA adapter
Core 0:      +51.0°C  (high = +86.0°C, crit = +100.0°C)

coretemp-isa-0001
Adapter: ISA adapter
Core 1:      +51.0°C  (high = +86.0°C, crit = +100.0°C)

coretemp-isa-0002
Adapter: ISA adapter
Core 1:      +52.0°C  (high = +86.0°C, crit = +100.0°C)

coretemp-isa-0003
Adapter: ISA adapter
Core 0:      +50.0°C  (high = +86.0°C, crit = +100.0°C)

and I check mods and i5k_amb is loaded:

root at lake:/home/szhang# lsmod | grep i5k_amb
i5k_amb                 5536  0

more interesting, I use a temperature monitor tool on Mac os, which is
http://www.bresink.de/osx/TemperatureMonitor.html

I was surprised find that it provide a lot of sensors reading, including
memory modules:

CPU Core 1: 39 C
CPU Core 2: 41 C
CPU Core 3: 39 C
CPU Core 4: 42 C
SMART Disk ST3750640NS P (3QD0H1Q0): 34 C
SMC AMBIENT AIR: 27 C
SMC AMBIENT AIR POSITION 2: 24 C
SMC CPU A HEAT SINK: 36 C
SMC CPU A PROXIMITY: 27 C
SMC CPU B HEAT SINK: 35 C
SMC CPU B PROXIMITY: 27 C
SMC CPU C PROXIMITY: 27 C
SMC CPU D PROXIMITY: 28 C
SMC DRIVE BAY 1: 32 C

SMC GPU 1 CHIP: 45 C
SMC MEMORY BANK A POS 0: 45 C
SMC MEMORY BANK A POS 1: 26 C
SMC MEMORY BANK A POS 2: 27 C
SMC MEMORY BANK A POS 3: 27 C
SMC MEMORY MODULE A1: 58 C
SMC MEMORY MODULE A2: 63 C
SMC MEMORY MODULE A3: 60 C
SMC MEMORY MODULE A4: 56 C
SMC MEMORY MODULE A5: 57 C
SMC MEMORY MODULE A6: 55 C
SMC MEMORY MODULE A7: 51 C
SMC MEMORY MODULE B0: 54 C
SMC NORTHBRIDGE CORE: 118 C
SMC NORTHBRIDGE HEAT SINK: 79 C
SMC PCI SLOT 1 POS 1: 44 C
SMC PCI SLOT 1 POS 2: 46 C
SMC PCI SLOT 2 POS 1: 44 C
SMC PCI SLOT 2 POS 2: 47 C
SMC POWER SUPPLY POSITION 1: 33 C
SMC POWER SUPPLY POSITION 2: 49 C
SMC POWER SUPPLY POSITION 3: 36 C

but with Mac os I can't do anything about my project...

so how can I get the memory temperature in ubuntu?

Any help is greatly appreciated. Thanks.
