Answers own query... :)

The problem turned out to be that whilst the as99127f-0-2d chip 
requires the w83781d kernel module, any settings like "set fan1_div 
8" in the w83781d section of /etc/sensors3.conf seem to be ignored 
because the as99127f has its own dedicated chip section.

Also worth mentioning that sensors are broken for this motherboard 
with the latest Karmic Koala kernels [2.6.31-6-generic and 2.6.31-2-
rt].  Errors from dmesg:-

 ACPI: I/O resource 0000:00:1f.3 [0xe800-0xe80f] conflicts with 
ACPI region SM00 [0xe800-0xe806]
 ACPI: Device needs an ACPI driver
 i801_smbus: probe of 0000:00:1f.3 failed with error -16

The workaround is to add the boot parameter 
Hope this helps someone.
