They crash into each other when you try to apply both of them.

I think your patch may have done more than you think. It not only removed
coprocessor instructions that are not supported by ARM7TDMI, but also removed

You were certainly correct to remove certain coprocessor instructions like ldc2

I'm not sure we're allowed to remove *all* coprocessor instructions.
