The kernel's acpi implementation in /proc is very slow. I am not clear on how much of the delay is real CPU load, most of load might be due to waiting for a slow ACPI system. In wmbattery's acpi support, I found it best to allow the delay between updates to be tunable by the user, and make the default for ACPI 3x as long as it is for APM. At least this keeps the apparent load average down. It's also possible that this program is doubling the time of each update by reading the acpi info files when it only needs to read the status files. -- see shy jo
