Try switching SATA Config to AHCI mode in the bios. I also have the same board as you. I got tired of getting that " still waiting for......"

SO I purchase WD360 35.6 SATA drive Raptor.

I switch sata config to ahci mode in bio. Then during loading up my IPC 10.5.6 , i press F8 and type in " -v -f " and it load up to install screen do what I need it to do . You have to install voodoo 9.5.0 and seatbelt.kext so there won't be any problem during installing. install done and restart and press f8 again and type " -v -f " then it load to the OSX intro and there setup your profile and your done and it will load the desktop screen.

Now I need to install chipset driver so It could recognize my IDE drive.

8800 GS with full power using EFIstudio to install the driver.
