I can see your argument on blindly supporting it, Haiku checks for it and cpu frequency and stops booting if it is missing. I could just change haiku's code to not require it.. but:
- I'd rather have the information then not (even if it is just 0)
- the parameter exists on *every* Apple openfirmware implementation (i've verified this on a G3 bronze powerbook, G3 iBook, G4
QuickSilver, G5 iMac)
- as the parameter exists on all new-world Apple systems, who knows
what other operating systems this breaks compatibility with?
For what it's worth, Sun systems don't (currently) use a "bus-frequency" property. We do have a "stick-frequency" property, which relates the "stick" register to real-time nanoseconds, but that's specific to the sun4v series of platforms.
