Looks good so far.

Next step is to burn the ISO to a DVD, then boot from it, choose your language go ahead to menu and lunch the disk utility & partition your HD - you will need an empty HFS+ / MacOS Extended Journaed Partition with atleast ~10GB. Follow the setup until the screen, where you select this partition - don't continue right away with installation from here - instead click on Customize button - dialog should look like this: http://awevo.net/wp-content/uploads/...ccbfbf09e6.png
I would only select a bare minium of the avaible fixes like this:

iATKOS v5i Main System
PC EFI V9
dsmos
Disabler.kext
PS/2
OHR
Intel SATA
Laptop Battery

If everything wents fine you shoudl be able to boot after install - for the GFX, I would later install either nvdarwin.kext or create a EFI String with custom NVCAP. LAN should work out of the box - I am not sure about the wireless, but there are people having Atheros cards with 0x168c device ID working vanilla.
For the sound you can either try with VoodooHDA.kext - or if you want the input jacks or an internal mic to work also, I would recommend to create Linux codecdump and patch AppleHDA using Tarugas Patcher App. (Search for a codec*** file in /proc/asound/card0 - mine is for example codec#2 yours might be different, then use "sudo cat /proc/asound/card0/codec#2 > ~/dump.txt" copy dump.txt from the Linux users home directory and drop it into the patcher icon.)

Good Luck.
