0.2 will overwrite the installation of the script (but you can just install it again). The new version of pete's startup script does properly detect and automatically uses the minimum and maximum supported CPU speeds (and it WILL automatically update the speed when you change kernels, now). It's using the same method my script used, but doesn't allow you to modify the speed - it only uses the minimum and maximum supported. Previously, the speed was being hard-coded, and the new maximum speed was being included in the kernel update. Was I Pete's inspiration for this change? The script in the first post should still work, however, if you want to customize your min/max speed. I am also working on a new script in a different format: setmax XXX setmin XXX setgov xxxxxxxxx When you type any of those by itself, it will list off all the available speeds (or governors), including the virtual speeds of "max" and "min". When you set one, it will take effect immediately and be applied on reboot. I'll have that posted tomorrow sometime for people that are interested in customizing their speed. For now, the script in the original post should still work fine!
