Yay, so here's what does and doesn't work:

Works: Sound - I left VoodooHDA checked, hopefully this won't kill the kernel as some have reported it has...

Works: USB - all of the ports work 100%

Works: Ethernet. Even got a $30 Ralink Wifi-N card working perfectly.

Everything except the Radeon 3450 works - stuck in 1024x768.
