I just installed Gentoo on my iBook :)
Everything seems to be ok. But cpuinfo shows _very_ low bogomips.
Altough, if i start form install cd, then cpuinfo shows about Cpu Hz x 2, as it should be (at least according to bogomips howto)...
Is what ok ?

You've installed a newer kernel than the one on the LiveCD. In 2.6.16, the timing loop code was rewritten and now BogoMIPS mean absolutely nothing. It's fine. See this post for info:
