Since the Mac IIci has a 68030 CPU which includes floating point, I tried 
to build a kernel that didn't have FPSP or FPEMUL options in the config 
file.  The kernel built OK, and it booted in single-user mode, but as 
soon as I tried to answer the "what shell do you want?" question, it hung 
up solid.  Couldn't even use the interrupt (NMI) switch to get into the 
debugger to find out where it hung!

So, is this a known problem?  Are we stuck with it long-term?  (That FP 
code takes up a good 40-50KB that could be put to better use...)
