I think under KVM I was mostly doing primary passthrough, so it's different. On 
Xen it's generally been secondary; I may re-try again with the ATI patches at 
some point, but I've not had much success and the faux 'quadro 6000' is working

The 3210 chipset is its own special beast, based on, but not exactly the same 
as X38. I think most, but not all X38 motherboards do not work. The exceptions 
are, I believe, the Intel 38BT and if I remember correctly there's a third 
party (DFI? Gigabyte?) That supplied a beta BIOS that made things work.
