If you aren't too crazy about which distro, RedHat Fedora Core 5 [Bordeaux] set up (AND BOOTED!!) with out a glitch on my via sata raid 0 and opteron 242*2. Could be best to get it and go on, at least for now.
Eventually maybe we'll have answers to why 64-bit technology and sata raid has been so lagging in support. Our hardware will be outdated before working solutions arrive. Anyone know if there is a 64-bit flash plug-in?
