This is my laptop cpuinfo, but I think it shows too few Mhz. I know it's a mobile proc, but isn't it suppose to raise the clock when compiling? I'm installing gentoo from the RR4 LiveCD, right now, so I suppose the CPU clock should be set at the maximum value.

Now I've booted my new system, and cpuinfo shows the correct clock. But I still don't get it why it showed that way,from the livecd.

It should show that way if it is a laptop. If you new install now shows the same mhz all the time then you should probably go back and recompile powernow support in your kernel so you dont set something on fire 
laptops are capable of lowering the mhz when the processor isnt in use so they dont run as hot. this helps the the components have longer lives...

I don't now much about cpu-frequency scaling, but I would like to enable it in the kernel. Is this a good config? :
| Code: | │ │ [*] CPU Frequency scaling │ │
│ │ [ ] Enable CPUfreq debugging (NEW) │ │
│ │ < > /proc/cpufreq interface (deprecated) (NEW) │ │
│ │ Default CPUFreq governor (userspace) ---> │ │
│ │ < > 'performance' governor (NEW) │ │
│ │ < > 'powersave' governor (NEW) │ │
│ │ --- 'userspace' governor for userspace frequency scaling │ │
│ │ [ ] /proc/sys/cpu/ interface (2.4. / OLD) │ │
│ │ <*> 'ondemand' cpufreq policy governor │ │
│ │ <*> CPU frequency table helpers (NEW) │ │
│ │ --- CPUFreq processor drivers │ │
│ │ < > ACPI Processor P-States driver (NEW) │ │
│ │ < > AMD Mobile K6-2/K6-3 PowerNow! (NEW) │ │
│ │ <*> AMD Mobile Athlon/Duron PowerNow! │ │

│ │ < > Transmeta LongRun (NEW) │ │
│ │ < > VIA Cyrix III Longhaul (NEW) │ │
│ │ --- shared options │ │
│ │ [ ] /proc/acpi/processor/../performance interface (deprecated) (NEW) |
