I think Xscalular is free. I will check it out on Pocketgear.com and post here.
If you want to look at Pocket Hackmaster, you can go to
http://www.pockethackmaster.com and there are links for Palmgear and Handango.
I am not proficient enough with Pocket Hackmaster to get it to scale the way I want with the faster bus. I know it is me, not the overclocking software. I can hard set it for the right speed, but can't seem to set it correctly fo scaling with CPU load.
Also, I think the trial version of Pocket Hackmaster may not let you enter the manual values.
