I've got 5.8 standard installed, and most of it working. I have hit one or two oddities, however...
First, I found that the wrong speedstep module was loaded, so I blacklisted it and used /etc/rc.modules to load both ibm_acpi and speedstep_centrino, which are the modules that I need for my IBM T40. I started Vcpufeq and se it for ondemand, told it to save on exit, and to start on boot.
Trouble is, it doesn't start on boot, I've had to start it manually each time I've rebooted the machine.
What am I doing wrong? How do I go about getting the CPU throttling to work automatically?
