I have a similar error with Asus P5N-VM WS/TW100-E5. The error did no appear until I updated the Bios. Previous Bios prevented x64 operating systems from seeing 8gigs of ram, or in the case of non linux OS prevented them from installing.
After Bios update I am getting the nforce2_smbus errors. Also my Nvidia drivers have crashed and I cannot load the nvidia settings, nor do both of the nvidia cards work simultaneously anymore, probably due to the driver crashing. They did under previous bios, but Ubuntu Lucid was unable to see more than 2.9 gigs of ram. original bios P5N-VM-WS/TW100-E5-BIOS-0405 -> No nforce2 error with this bios version updated bios P5N-VM-WS-BIOS-0601 -> error started after update to this bios version "1. A fix to system would not be able to install 64-bit OS when more than 4GB memory" Don't know if this information helps.
