Some finding : The Terastation is using a EMC6D102 chip to control the FAN (FAN Control EMC6D102 initialized)and to monitor the voltages. Buffalo added a driver for that chip in the 2.4 kernel, but in 2.6 kernel, this chip can be handled by the LM85 probe driver ! This hardware chip is not present on a TeraStation Pro !

This page explains how to use the kernel 2.6 LM85 driver. I'll use that to update the ts_fan.c file (BUFFALO INC. FAN driver ver 1.00)
