OK, so it worked fine.

No, if you see the SMBus now then you have all the patches you need.

This is where the other D510 have a hardware monitoring chip. Instead,
all you have are the SPD EEPROMs. You can play a bit with the
decode-dimms script, but that's probably not what you want.

But apparently this isn't the case. What form factor is the USDT? If it
is a small thing, then maybe they had to cut on extra features to make
it fit.

Sorry but this looks like a dead end. I can push the patch upstream for
SPD EEPROM access, but that's about it.
