1) Does my PowerBook support cpu scaling? How do I enable it? Can I even make it run at 500Mhz or so?I think it runs at either half-speed or full speed. You need to enable cpufreq scaling in the kernel.
Do I have to recompile kernel? How do I enable cpufreq scaling in the kernel?
No, one is enough.
Thanks!
2) I would really like to be able to suspend my computer. I know that I can't suspend to ram because Nvidia (I have Nvidia Geforce 5200go) doesn't release drivers for PPC. (at least that's what I've been told) I'd love to be able to suspend to disk... can my PowerBook do that? Does it need a particular kernel?Yes. I don't think it was possible with kernels before 2.6.12 and there seems to have been a regression somewhere around 2.6.15, so any kernel from the 2.6.12-14 series should work.
Bad news...
What do you mean? I don't think my airport express card is actually supported.The bad news is that you'll need a newer kernel for wireless.
I have kernel 2.6.15-4
hope that helps.
Thanks! Marco.
