Actually, believe it or not, I got it working. I realized that I was using GCC 3.0.2 to compile up the lm_sensors modules, but the i2c modules (2.6.1), which are part of the kernel, were compiled with GCC 2.96 (RH 7.2). Now, when I went back and recompiled everything using GCC 2.96, I was able to get it to work. I had to insert the modules by hand, but, after all was said and done, lsmod gives: eeprom 2960 0 (unused) gl520sm 6688 0 (unused) i2c-ali1535 4080 0 i2c-dev 3616 0 i2c-proc 6128 0 [eeprom gl520sm] i2c-core 13248 0 [eeprom gl520sm i2c-ali1535 i2c-dev i2c-proc] And, from there, sensors gives decent output! Thanks a lot for a great app! -Rich
