Comment (by daniel):
Haven't calculated what the worst case is, perhaps it is not that much.
You can probably get that from the GRFPU manual.
It seems like a good idea to do it at the same time. I still think one
should store FSR before disabling FPU, but of course if the execution time
of the trap handler is longer than what can be queued in the FPU pipeline
it shouldn't be a problem...
