This question was answered a few years back, but on an Intel
Mac this path does not exist.
It seems like on Intel the path would be
“:/rom”, with the key being “version”, as that data
matches what System Profiler displays for its Boot ROM Version field on my
Intel dev machine.
Is there any official information on how to get this (I
couldn’t find much searching for it)? I can code things to look for the
PPC path first, then fall back to the location I’ve found it on my Intel
machine, but this is just what I’ve found poking around myself, and who
knows if I can rely on this for all machines.

You can create a matching dictionary for this using:
IORegistryEntryFromPath(kIOMasterPortDefault,
kIODeviceTreePlane ":/rom/boot-rom");
