Looking at saving some power, wondering if anyone has already compiled KLH10 on an ARM based system and what kind performance has been seen.
Thanks

Thanks MRR. I have KLH10 KL with Panda distor up and running on the pi.
I don't have the networking set up properly yet, still tweaking the config on the pi running squeeze. Thank you! I used your notes to compile the source, and it compiled properly.
Have not had as much success on the dreamplug, but have not had much time either. Will post when it is up and running. I can make the ARM binaries available if any one wants copies.
Thanks!
