Running a couple of tests I have discovered the stock kernel is set to never let the cpu run slower than 640 mhz.

The knock on effect of this is that the cpu in general use is always running between 700 - 800MHz.

I don't consider this to be energy efficient, and will be producing a custom kernel to fix this.

when the kernel source is fixed up as references are missing, if you buy a MoDaCo Ad-Free subscription I'll work quicker :D

After the kernel will work, and you can thank for this material, do not want to buy a pig in a poke!

the 2.6.38 source is incomplete, so I've started work on the L5 kernel sources, going to get a 3.0.8 kernel built

It differs in that I built it myself.

Will look at overclock and stripping unnecessary stuff and adding ext 2 3 4 support

may i ask what specificic firmware you're using to tell that the minimum frequency is 640MHz?is it the old or the latest or what?as for me having v10b(ph firmware),the benchmarks says it has a minimum frequency of 320MHz only and 800MHz max.hmmm.why you're telling that min. freq is 640MHz?or why don't you just extract karnel builds from other firmware?sorry for my english.i'm new here.
