This diff makes sunffb work on my blade1k, which has:
creator0 at upa0: Creator3D, model SUNW,501-4788, dac 10
I added the necessary .register ops to the .s files to make them compile and
nicked a fix from NetBSD to keep the FPU enabled to avoid fpu traps
that made the driver unbearably slow. Need to investigate that, maybe
the kernel isn't handling this properly.
