Hello Idwer Vollering,
I came across an old mailing list item concerning the H8SGL Opteron motherboards.
https://mail.coreboot.org/pipermail/coreboot/2013-April/075629.html
Is it truly the case that the single socket boards are already supported by Coreboot (as well as the C32 Opteron version)? I cannot find any other information about these elsewhere. Any information that you might have would be extremely appreciated.

Some boards are supported, those mentioned here and in the subject line seem absent. See https://www.coreboot.org/Supported_Motherboards and https://github.com/coreboot/coreboot/tree/master/src/mainboard/supermicro for what is up-to-date.
It wouldn't be very difficult to add support, all you really have to do is change IRQ assignments and HT mapping etc, I myself am working on a port of the H8SCM to the native coreboot code as the AGESA version doesn't have IOMMU support.
There are several supermicro boards that are better than the ASUS D8/D16's, as they have dual northbridge (more pci-e lanes), better onboards nics, onboard SR-IOV RAID controller etc and of course they are newer (2014 vs 2010)
I wouldn't recommend putting in the work however as they won't support the upcoming OpenBMC like the asus ones although you could maybe replace the onboard BMC BGA chip to get it if the pinouts are the same for both.
The best G34 board period is the H8QG4-LN4F.
