But it would be great to also consider what the user story is for people who want to use this on other mainboards.
Ideally it shouldn't be neccessary to buy a niche product like a RAM breakout adapter; it would be great to also explore more ways to access the SMBus signals, e.g. PCI Express optionally has SMBus, smart batteries have it, etc.
The VGA and HDMI interfaces also use the SMBus. Theoretically we should be able to use a VGA[3] cable and expose the wires of pins 12(SDA) and 15(SCL) to access the bus. I can test that proof of concept if I complete the project earlier than expected.

Thanks, Husni.
