I just defined the other config words as colon definitions, but I’m pretty sure now that isn’t working correctly.

I hate to be a bother, but when you find the time, if you could try and implement the other config words, that would be great.
Yes I will try my best, although I still have a backlog from the past few months to get on top of at the same time - any patches appreciated :)
One thing I did notice on my travels though: https://git.qemu.org/?p=openbios.git%3Ba=blob%3Bf=forth/device/other.fs%3Bh=...
Looks like the r* words are currently missing an implementation.
Note that rb@ etc. are bus-specific. h# 230 get-token and all that.
While we're at this topic: Note that there are also some bad fcode ROMs around which use the non-register memory access functions for accessing MMIO memory. SLOF has an ugly work-around included to get these working:
Note sure whether this is applicable for your PCI card, though.
