FS#4075 - Cpufreq is missing on kirkwood target, so the cpu is stuck at lowest frequency #9057

Hello, I installed openwrt on a Zyxel NSA-310 device. Everything seems good but when I went to test the performance it was not so good.
So I noticed that the cpu frequency is stuck on 200MHz and cpufreq is missing (also can't find it as a kmod package).

I am running on original u-boot because of a bad block and the wiki suggested not to flash it. Maybe openwrt's u-boot has a workaround on this or there is some setting to apply on boot?

BTW I think the wiki does not include a safer, less invasive method as this device can boot entirely from usb without flashing anything, but to do so you need to have a kernel/initramfs w/usbstorage included.

I might try to compile openwrt from sources to include cpufreq. Should I then submit a pull request or a patch?
