Please, try w/ gentoo-sources-2.6.17-r2 (and/or latest vanilla) and report back. If it still doesn't work, attach your kernel .config and post emerge --info.
i tryed with 2.6.19-rc6 and there is the same bug
Please compile CONFIG_CPU_FREQ_DEBUG into your kernel and boot with the cpufreq.debug=3 parameter. Run "dmesg" and note the last line of output. Then, "echo 700000>scaling_setspeed" and see which lines were added at the end. Then run the echo again, and see which extra lines appeared in dmesg that time. Finally, save dmesg to a file and annotate it where you saw those events happening. Then attach it here :)

Hmm actually I think it's much simpler than that. Try: echo "700000" > scaling_setspeed note the "" marks
reopen if my judgement in comment #6 is wrong
