I have a Celerom M 2.5GHz Toshiba Satellite A10 laptop. I installed Ubuntu on it and keep it more or less updated since 4.04 was released. I have just upgraded to dapper yesterday, and -appart from some cool and unexpedted upgrades, like full out-of-the-box synaptics touchpad support- I have found a quite strange problem.
You see, With the default kernel that hoary shipped, I could load some kernel modules and get full speedstep support. To be more precise, speedstep-lib and p4-clockmod modules. I had like eight different CPU frequencies to choose from, which was great: 15 minutes of unreal tournament at full CPU freq (2.5GHz) means CPU heat pumping up to 82ºC!
With this option, I could set CPU freq to, say, 1.25GHz and still be able to play games or something like that with CPU heat arround 55ºC.
The problem is, I have upgraded to dapper default kernel, and all my full range of freqs to select from has just been reduced to 2.5GHz or 2.1875GHz.
Totally unacepptable, taking into account I still use this machine for (classic) gaming (Q3A isn't death yet... :P ).
Does anyone knows how can I get back all the supported freqs of my 2.5GHz pentium Celerom M with my 2.6.15-20 kernel?
( And don't tell me the CPU doesn't support if, I positivelly know it can do what I ask for. It has been doing it for two years now. )
