Print a message if bootverbose that the emulator is present in the kernel.
Move the initialization before isa_configure() and npx, in case npx does
something to initialize the state of the emulator somehow.
I do not have any machines without a FPU so that I can test this with -
except an old 386sx motherboard in a box somewhere that might work...
