I'm pretty sure the > answer to your question is "Yes" (because that is the default?) No, the answer is "no", because GENERIC contains a disabled apm device. You need to completely remove it, not disable it, because just compiling it changes some code in other parts of the system. Specifically, make a copy of /usr/src/sys/i386/config/GENERIC, calling it, say, /usr/src/sys/i386/config/NOAPM, and remove the following line: # Power management support (see LINT for more options) device apm0 at nexus? disable flags 0x20 # Advanced Power Management Build a new kernel, install, reboot and all should be well.
