Indeed!  It's interesting to note that I have seen what appears to be
funny behaviour with FP code (both of the boards running this code use
the kernel FP emulator).  Perhaps lwc1/swc1 aren't used that much...

I've changed both of these to

-	inst = fuiword((u_int32_t *)frame->f_regs[PC]);
+	vaddr = frame->f_regs[PC];	/* XXX truncates to 32 bits */
+	inst = fuiword((u_int32_t *)vaddr);

Thanks!

Simon.
