I have the same motherboard.

make sure you have the latest bios. Your motherboard most likely has a 1205 revision. The latest is 1405. After I updated the BIOS, zephyroth's DVD booted and I was able to install. However, with his motherboard, you are going to have a problem with the installation freezing at 1 minute. When it does, it will reboot itself eventually, so boot back up the DVD again, and just continue the installation. It will say something like "this will take about 115 megs of space" when you go to install again. It will be done with about 2 minutes. You'll be able to boot into your newly installed Leopard now, but then it will get stuck at "Creating your account" after submitting all of your account info. When you do a hard reboot after that and try to login using your acount, the desktop will start to load then will kick you back out to the login screen again and again until your pc eventually crashes. I've even tried using the firwire account transfer from my iMac to my AMD machine, and that froze too.

Best bet is to wait for Rev. 2. Don't jump for the 10.5.2 release as it has broken some packages.

ANd I KNEW I was right about my motherboard being popular!
