Stuck on PCI Configuration Begin - OS X Yosemite

Vanilla install of course, I can't even get into the installer.
Here are my specs:
Mobo: Gigabyte 945GCM-S2L
Processor: Intel Pentium Dual CPU (E2180) @ 2.00GHz
Graphics Card: ATI Radeon HD 4350

I know, it's very very old, it's just a project and also a personal challenge. I've tried all sorts of boot args (dart=0, npci=0x2000, npci=0x3000, PCIRootUID=1, PCIRootUID=0) but they don't work. Any ideas?
Here's the whole log:

Thanks in advance!
