 Unfortunately, no. Most of this information is regarding 9.04 and older.
 E.g. via-sdmmc is now part of the standard kernel and e_powersaver should
 not be used at all:
 [http://marc.info/?l=linux-kernel&m=124444806413489&w=2]

 There is just one way to disable acpi-cpufreq for a original Ubuntu Kernel
 - Completely disable ACPI. Therefore you have to add "acpi=off" to your
 kernel boot parameters. But thia disables all ACPI features, so you may
 want to compile the kernel on your own.

 You may follow these instructions:
 [https://help.ubuntu.com/community/forum/software/CustomKernel] or
 [https://help.ubuntu.com/community/forum/software/CustomKernel]

 And as you already recognized, you have to disable the kernel config
 option CONFIG_X86_ACPI_CPUFREQ.

 Kind regards,
