This used to work in my 3.3 based kernel. btw, once it locks up... retry with your 3.3 based kernel (hold reset and swap sd card's, the "bug" should lock up again when trying to set 800Mhz on bootup.. In my testing, once it locks up, any cpufreq enabled kernel will keep locking up... Makes you wonder if a pll setting isn't getting reset on bootup...) I've traced it to the "arch_clock->clk_set_rate(clk, rate);" call in the "int clk_set_rate(struct clk *clk, unsigned long rate)" function http://git.kernel.org/?p=linux/kernel/git/torvalds/linux.git;a=blob;f=arch/arm/plat-omap/clock.c;hb=HEAD#l132 at that point, I'm a little lost in the omap36xx code..
