I am not brave enough to try a new kernel yet. I have this rig running great on what is a starndard kernel source with a few modules removed that were not needed. But even that took a few trys and a kernel panic
I would hope that Nvidia didn't change the sound or network much for the 64 but there again I am just on a standard nforce 2 not an nforce 3 system.
Play with it on a small old harddrive until you get it right then set it up on your current ata drive
