After having similar problems to others with getting the package to compile, I read into your support answers a little more closely. It seems that the issue compiling from I2C_DRIVERID_ADM1024 not being defined is due to old header files, but the root cause may be that many people have a kernel-i2c rpm installed. This would get picked up, and caught me even though I have long since upgraded kernels, and uninstalled their predecessors entirely. -Dave
