In the i2c support section of the 2.5.65/66 kernel configuration, there doesn't appear to be any support for lm_sensors based upon the viapro. The vanilla-sources 2.4.20 with prior versions (before 2.7) of lm_sensors do work fine. The modules used are 'i2c-viapro' and emerging lm-sensors-2.7 does not work as the emerge stops with these messages: ============================================================= gcc -D__KERNEL__

This is a known issue as i2c is getting a makeover. Check the LKML archives for the discussion. This probably will be fixed in 2.5.67/68... Also, 2.5's module code has been redone, so you probably won't be able to emerge any 2.4 module ebuilds... Since development-sources is vanilla 2.5, I am closing this out.
