It works fine with 5.3 in here with nForce2, but only two things that  
aren't work...smbus and ethernet (tried NDIS and nvnet, but still not  
work). My motherboard is MSI K7N2 Delta2 Platinum (MS-6570E-010). I never  
have tried 5.2.1 with this new motherboard, because it's too old to touch  
it.
