The way configuration paramters are provided on Sun systems is via openfirmware properties, this is how they do everything and that is why they never setup the NVRAMs on various chips. This happens on PowerPC too. One of many examples is determining the clock parameters of the ATI Radeon graphics card, it's provided as an openfirmware property not in some config area in the BIOS. We can either be anti-social and _demand_ that these systems get their NVRAMs fixed, which in reality will never happen and is totally unreasonable, or we can say ok this is how we get the information we need on these platforms we'll look for it there.
