RB411U

> 3. if possible, whether or not RouterBOOT offers a “cpu frequency” setting (typically under key ‘f’) at boot time

Select CPU frequency:
   1 - 100MHz
   2 - 150MHz
   3 - 200MHz
* 4 - 300MHz

> 4. if possible, for various cpu frequency settings (ideally for all of them), the output of `dmesg | grep Clocks; hexdump -C /dev/mtdblockN` where mtdblockN is the soft_config partition. Please provide this output at least once, even if there’s no frequency setting.

300MHz
