This is going to sound wierd, because it means you would need to include replacement trap() and trap_pfault() code, but... Any chance of writing this as an LKM? This would allow binary patch for those people who can't/won't recompile their kernels, and would make it an administrative choice. It would also make it easier to carry between versions (I thought of this because you used a SYSINIT() for it). I've often thought that the FPU emulator should be done this way, and the math libraries and FPU instruction inlining not be special cased...
