There is a new BIOS out for the Sabertooth line of motherboards which is available on their FTP server. This is version: 0813 and does not have any official changelog or notes yet, however, I have inquired and received an email stating the following:
The 0813 beta BIOS has been released for those who are having certain compatibility issues when installing the new 'FX' line of AMD CPU's. For most part the BIOS is the same as the 0810 beta release with the exception of new CPU Micro-code information that has been modified and added to resolve the FX CPU compatibility issues. While still in beta phase, users who are having problems with this can [at their choosing and risk], install this BIOS which should iron out several issues.

I have installed this BIOS without any problems whatsoever. If you are having issues with the FX series of CPU's, you might want to give this a try. The file should be showing up and officially supported shortly on the Asus website.
