Intel Desktop Board D875PBZ

I have this board, lspci dump:
0000:00:00.0 Host bridge: Intel Corp. 82875P Memory Controller Hub (rev 02)
0000:00:01.0 PCI bridge: Intel Corp. 82875P Processor to AGP Controller (rev 02)
0000:00:03.0 PCI bridge: Intel Corp. 82875P Processor to PCI to CSA Bridge (rev 02)
0000:00:1d.0 USB Controller: Intel Corp. 82801EB/ER (ICH5/ICH5R) USB UHCI #1 (rev 02)
0000:00:1d.1 USB Controller: Intel Corp. 82801EB/ER (ICH5/ICH5R) USB UHCI #2 (rev 02)
0000:00:1d.2 USB Controller: Intel Corp. 82801EB/ER (ICH5/ICH5R) USB UHCI #3 (rev 02)
0000:00:1d.3 USB Controller: Intel Corp. 82801EB/ER (ICH5/ICH5R) USB UHCI #4 (rev 02)
0000:00:1d.7 USB Controller: Intel Corp. 82801EB/ER (ICH5/ICH5R) USB2 EHCI Controller (rev 02)
0000:00:1e.0 PCI bridge: Intel Corp. 82801 PCI Bridge (rev c2)
0000:00:1f.0 ISA bridge: Intel Corp. 82801EB/ER (ICH5/ICH5R) LPC Bridge (rev 02)
0000:00:1f.1 IDE interface: Intel Corp. 82801EB/ER (ICH5/ICH5R) Ultra ATA 100 Storage Controller (rev 02)
0000:00:1f.2 IDE interface: Intel Corp. 82801EB (ICH5) Serial ATA 150 Storage Controller (rev 02)
0000:00:1f.3 SMBus: Intel Corp. 82801EB/ER (ICH5/ICH5R) SMBus Controller (rev 02)

I couldnt find any info on the lm-sensors website about this
hardware.


sensors detect said:
Bus `SMBus I801 adapter at c800' (Algorithm unavailable)
Busdriver `i2c-i801', I2C address 0x2e
Chip `SMSC EMC6D100 or EMC6D101' (confidence: 7)

and also to be written:
ISA bus address 0x06e0 (Busdriver `i2c-isa')
Chip `Nat. Semi. PC87372 Super IO Fan Sensors' (confidence 9)

and with these modules and the force (as recommended by ruik from IRC)
modprobe lm85 force=0,0x2e
modprobe i2c_i801

sensors will output:
lm85-i2c-0-2e
Adapter: SMBus I801 adapter at c800
V1.5:       +1.50 V  (min =  +0.00 V, max =  +3.32 V)   
VCore:      +1.32 V  (min =  +0.00 V, max =  +2.99 V)   
V3.3:       +3.30 V  (min =  +0.00 V, max =  +4.38 V)   
V5:        +5.10 V  (min =  +0.00 V, max =  +6.64 V)   
V12:      +12.00 V  (min =  +0.00 V, max = +15.94 V)   
CPU_Fan:   2928 RPM  (min =    0 RPM)                     
CPU:         +44?C  (low  =  -128?C, high =  +127?C)       
Board:       +29?C  (low  =  -127?C, high =  +127?C)      
Remote:      +29?C  (low  =  -127?C, high =  +127?C)       
CPU_PWM:   255
Fan2_PWM:  255
Fan3_PWM:  255
vid:      +1.375 V    (VRM Version  9.1)


Presumably with the "to be written" bit i should be able to
alter the fan PWM ratios and ultimately the fan speed, which
would be very nice as i could put to rest a piece of hardware i
made which uses the serial port to do PWM!  I can't lend
hardware but i can help test any new drivers.

Thank you
