powernowd 1.00-1ubuntu5 (sparc binary) in ubuntu lucid

 This package controls CPU speed by using the sysfs interface to the CPUFreq
 driver in v2.6 Linux kernels. It does not depend on APM or ACPI,
 and it doesn't try to do anything other than control the CPU.
 .
 If supported, CPU speed is controlled entirely by the kernel, using
 the built in ondemand governor. The userspace daemon powernowd will only be
 used as a fallback.
 .
 The name is somewhat misleading, as any CPUfreq capable processor will work,
 not just those from AMD. However, it works better on CPUs that support more
 than two speed steps, like those with AMD's PowerNow! or Intel's Pentium M
 series.
 .
 The powernowd daemon is less complicated than cpufreqd or cpudyn, at the
 cost of absolutely depending on a 2.6 kernel with the userspace governor
 and sysfs support enabled.
