Your main problem is your kernel. when you boot up, download and install this: http://dl.nawcom.com/legacy_kernel-10.7.0.pkg.zip

Nawcom has created a kernel install package for us AMD users that patches all sorts of things including the busratio problem so you don't have to boot with that flag. Also a lot of the problems that would have normally been fixed with Marvin's AMD utility has been fixed with this package alone.

The only thing you will need to do afterwards is open up your applications folder and right click on safari and press get info. In that, check the run in 32 bit mode box. A 64-bit fix for safari on our machines has not been worked out yet.

As for sound, just try different kexts related to your mobo. Search for your specific modo model on the various HCLs around the community - someone has it working somewhere.

Thank Nawcom, Netkas, AndyVand, Rominator, BlackKnight, and a slew of others that have made running osx86 on AMDs. If you run into more problems search for these names on this forum, or head over to nawcom's blog or netkas' site. You will find everything you need.
