FS#587 - Driver p4-clockmod instead of acpi-cpufreq on EeePC 901
The driver loaded after the installation by the module cpufreq is wrong. In the Live version, it use the acpi-cpufreq driver, which is the good one for Intel Atom proc I guess. In the Installed version, the driver used is p4-clockmod so the cpu scaling frequency and power management is not done correctly.
