Fantastic guide aryajuanda, it helped me a lot with my snow leo installation.

FYI everything is working great just like on my old 10.5.8, though I had to place appleac97audio, voodoops2controller and nforcelan kexts inside /s/l/ext, as they won't load from the extra folder. The video card is injected via EFI string and my realtek card is working right out of the box.
Everything feels snappier, faster, hope it lasts.

Thanks again aryajuanda!!!

EDIT:
After a couple of days I must say that it's really behaving more stable and faster than 10.5.8, the only issue I've found (and not a big one) is that I cannot set the volume with the slider next to the clock or the keyboard, it seems to move but it turns back to the previous state once I drop the slider. The strange thing is that I can change it from the audio preferences :P

Any idea???
