I agree. I believe the performance of the interrupt handlers will not get
hurt because they are already different for MILO and SRM cases anyway.
The stuff in startup/shutdown is not performance-critical at all. So the
only penalty is a slight increase in the size of the kernel, which is
hardly an obstacle...
